  • The One-Knob Manifesto

    Duh Pedal
    Can you help me figure this thing out?

    It’s almost always a bad idea to label something a manifesto. It’s pretentious, and it makes you sound like a crank, especially if you were born between 1890 and 1990. But it is dramatic. And would anyone pay attention if I gave this post a more accurate title, like “Please Participate in My Stompbox User Interface Focus Group?”

    Anyway, I’ve been having this recurring workbench experience. (No, not the solder burns.) Every time I breadboard a stompbox project, I poke through the circuit, looking for places where I might add a switch or knob to unlock cool sounds. I usually find nice variations and build accordingly. But as soon as I plug in the pedal, I always seem to like one setting a lot more the others. Then I rebuild, hard-wiring the preferred value and ditching the switch or pot. Eventually almost  everything I build winds up with only one or two knobs. (Unless I’m making it for personal use, in which case it often has no knobs.) It’s not a love of minimalism, and it’s certainly not an assumption that users are too stupid for anything more complex. It’s just that time and again, the simplest solutions sound best to me.

    Meanwhile, I just had an interesting experience reviewing a (gulp) $5,000 amp for Premier Guitar, which crystallized some of my thoughts. The amp in question is a Little Walter 50/22 (which is actually two independent amps in a single housing), and I’ll link to the review when it goes live in a few days. But suffice it to say that Little Walter amps draw their inspiration from the earliest Fender tweeds, and have minimal controls to match: one volume knob and one tone knob. Furthermore, builder Phil Bradbury all but advises against using the tone control, pointing out that vintage-stye tube amp tone controls are strictly subtractive, and that you get maximum impact and richness with the tone circuit wide-open. And Bradbury is right. As on many great vintage amps, the Little Walter controls are practically superfluous. If you locate the right sweet spot, you can park the controls there and make any needed gain or tone adjustments the old-fashioned way: by playing them. Dig in harder for more distortion. Back of the volume to clean up. Use your angle of attack as a tone control. Like that.

    But you don’t encounter many new-production amps that adhere to the philosophy. I get the sense that a lot of designers would like to create minimalist amps such as these, but they fear that the public wouldn’t get it. How could the one-knob amp possibly sound as good as the one with 11 knobs? But I suspect that the more experience you have with amps, the likelier you are to believe that simple sounds better. Now I want to build a great-sounding tube amp with only an on/off switch.

    Three knobs?! What, do I look like Einstein to you?
    Three knobs?!
    What, do I look like Einstein to you?

    I’m finding the same to be true with distortion/fuzz/overdrive stompboxes. For many players, the minimum complement of controls is gain, tone, and master volume. But almost every circuit I’ve explored sounds better without a tone control, and it’s hard to make a gain control sound great throughout its entire range. So more and more I find myself fine-tuning circuits to what I feel are the best gain and tone settings, hard-wiring them there, and then just slapping on a master volume for level-matching. (And if the pedal doesn’t add a great deal of volume, I often skip the master as well.) If you “tune” the distortion, you can control the gain perfectly well via your hands and guitar.

    “But,” I hear the inquiring player ask, “don’t you need a tone control so you can use the same pedal with different guitars?” (Sadly, I sometimes believe I’m hearing the voices of inquiring players when I’ve neglected my meds.) Increasingly, I think not. In almost all cases, there’s a sweet spot where a circuit sounds good on everything from a bright Tele bridge pickup to a tubby neck humbucker. Those extremes don’t sound the same, of course. But if you’re playing distorted on a Tele, can’t we assume that you want a bright edge? (And vice-versa with the neck humbucker.) And if you do want to modify the tone, isn’t doing so with via fingers, amp, or mixing board a better solution than using a tone-sucking stompbox tone circuit?

    Another example: I spent countless hours pursuing a stompbox vibrato circuit. (I mean true pitch-shift vibrato, not tremolo.) I’d obtained great tones, but I couldn’t get the effect to sound good at all rates and depths, because the perceived depth changes along with the rate. Finally, it occurred to me to go the one-knob route, using only a rate control, and letting that determine the depth. That may sound like a half-assed non-solution, but I’ll be danged if I didn’t suddenly have the most gratifying vibrato pedal I’ve ever played. Like the minimal controls on ’50s amps, the arrangement just worked.

    Other factors influence my one-knob attitude: Since I’ve spent much of the last few years in the digital guitar realm, analog guitar has become a refuge from that sometimes math-based approach. When I switch on the analog rig, my goal isn’t maximum user options, but a primal experience. Also, there’s probably an element of advanced-player snob appeal. I don’t know much about cars, bicycles, motorcycles, or sporting goods, but there’s probably a parallel between minimalist musical tools that demand a fair amount of technical  finesse, and vehicles and sports gear with stripped-down, featherweight, only-for-pros features. Not every bicycle needs a kick-stand, and not every fuzz pedal needs a gain control. (Or something like that.) Additionally, I hope to bring my pedal designs to market, and what a crowded market it is! Sure, it’s mainly crowded by clones, but many brilliant builders are creating complex mad scientist boxes. Maybe there’s a niche for one-knob mad-scientist boxes…

    I’m not sure it’s kosher to conclude a manifesto with questionnaire. But I’m eager to hear your replies to these queries—or anything else you feel inspired to add. Thanks!

    1. Do you tend to change tone settings on amps and pedals when you switch guitars?
    2. How often do you fiddle with stompbox knobs mid-performance?
    3. Do you use your guitars’ tone knobs much? If so, how and why?
    4. Does anyone out there actually use their guitar volume knobs to veer from clean to dirty sounds? Or is just the wishful thinking of pompous guitar “journalists?”
    5. Would you consider using a no-knob stompbox that pretty much requires you to use your guitar’s knobs?
    6. What’s your favorite Nickelback song?

  • Blood on the Workbench

    Small puncture, big pain.
    Small puncture, big pain.

    I was trying to decide which self-indulgent experiment fascinating project to demo this week when my hand slipped, driving a sharp soldering iron tip into the meat of my fretting-hand index finger. It didn’t hurt all that much—until I tried to play. Ye-OWCH! (No, of course I wasn’t using the tool properly! I was trying to pick loose a knot of wire with the iron’s tip rather than the recommended wire-picker-thingy.)

    So no guitar recordings for me this week while my poor l’il finger recuperates. But I’ll try to compensate for this dog-ate-my-homework post by sharing three works in progress. If they turn out well (and they might!), audio and video will follow.

    1. Lipstick Tubes Revisited. For more than a year, the generic Mexican Strat I fitted with lipstick tube pickups has lived, disassembled, in a filthy cardboard box next to my workbench, guilt-tripping me every time I fired up the soldering iron. There were a number of experiments I’d been meaning to perform on it, and in a spectacularly bad example of scientific methodology, I incorporated them all at once, making it pretty much impossible to discern what’s doing what. But I hear some things I like. Here’s what’s new (beside the blood spatters):

    lipstick_labeled

    Not everything is working as desired yet — but there are some promising directions here, and it’s so nice to have a lipstick tube instrument again. :pacman:

    Joystick fuzz: like giving a loaded gun to a monkey.
    Joystick fuzz: like giving a loaded gun to a monkey.

    2. The Joy of Stick. Anyone tried a joystick effect, like Devi Ever’s Drone Fuck Drone? I bought a few joysticks from 4Site and have been having a blast. I thought they’d be difficult to wrangle, but it’s really just two pots, each with the standard three-lug connection, deployed in X/Y configuration. Two things to bear in mind, though: They’re generally available only with identical resistance values for each pot, and more important, you need two controls that have meaningful values throughout their ranges. Fortunately, I had just the circuit for it: my Filth Fuzz (which Fuzzbox Girl was kind enough to demo and review in 2011). I’d even labeled the controls X and Y! (I’m not selling these, but I do hope to bring it to market before long. Honest.)

    3. A Reanimated Amp.  This one’s personal: I’m finally refurbishing the 1951 “TV front” Fender Deluxe amp that I received for as a bar mitzvah present in the ’70s. (I was mature enough not to express my disappointment over getting some crummy old tweed. But how I longed for that shiny post-CBS crap!) My mom procured it from the son of one of her fellow elementary school teachers, who worked at Fender in nearby Fullerton. (Sadly, I’ve forgotten his name.) I also got to pick from three early-’70s Fender guitars: a sunburst Strat, a paisley Tele, and a black Jazzmaster. I, of course, chose the Jazzmaster — at the exact moment when no one on earth gave a crap about that model.  And naturally, I sold it just when new wave arrived and Jazzmasters became cool again. See? I established my pattern of buying and selling the wrong things at the wrong times while still in my teens!

    I didn’t wreck the amp by myself — the process started with the black paint job it acquired long before I entered the picture. Over the years it received a preamp mod from Paul Rivera, and later got totally ruined by an overambitious repairman who added mods I never requested, and who probably stole most of the original electronic parts. But the cab, chassis, speaker, and output transformer are original, and there’s no reason why it shouldn’t sound bitchin’ after I restore it to its original 5A3 circuit. I’m getting expert help from Tube Depot’s Rob Hull, who helped me source parts and make a grommet board to house the components.

    So my apologies for all talk, no audio. My boo-boo is healing, and I should be back able to, like, actually play some of this stuff soon!

  • A Lo-Fi Acoustic Guitar Pickup

    Part acoustic, part electric—but 100% bitchin'.
    Part acoustic, part electric—but 100% bitchin’.

    This post is inspired by in interview I just did with Mississippi Allstars guitarist Luther Dickinson, a cool dude and a deep player. I’m digging the band’s new album, World Boogie is Coming. (And for better or worse, that praise comes from someone who hates almost all modern blues albums.) You can read the interview here.

    Anyway, Luther was talking about how his entire style is a quest to create a loud, electric version of acoustic country blues. He mentioned how he was more drawn to the Mississippi blues players who went electric by slapping DeArmond pickups on their acoustics, as opposed to, say, Muddy Waters, who swapped his acoustic for a Telecaster. Luther also mentioned that DeArmonds are still his favorite way to amplify an acoustic guitar

    At some point it occurred to me that I’d never actually played an acoustic with a DeArmand. So I picked up a 1950s RHC-B and popped it into my old Martin 0-18. Have a listen:

    I’m a longtime fan of magnetic pickups on acoustic guitars. I had a Sunrise in my Lowden for 15 years and loved it, but it croaked last year. I replaced it with one of those hybrid models that combine a mag pickup with an internal mic, and it works fine. But after a year or so, I don’t think I’ve ever used the mic sound. I just like the way the mag pickup sounds.

    But is it still acoustic guitar? I’m not sure. I increasingly view amplified acoustic as a guitar category unto itself, residing somewhere between acoustic and archtop.

    And the DeArmond? Between its noisiness and reticent highs, it’s probably not the best choice for every occasion. It’s also a bigger pain to install and remove than modern mag pickups. But I dig how it sound in the video, and I’m definitely keeping it!

    So what’s you experience with amplifying your acoustic guitars?

  • Was J.S. Bach a Punk?

    bach_kitty

    Oh, my.

    But for better or worse, I like being reminded that superhuman geniuses weren’t necessarily super in every regard. Maybe because it gives the rest of us hope or reassurance? Plus, it’s too easy to typecast artists into archetypes, like so:

    Paragon: Bach, Verdi, Palestrina, Beethoven
    Punk: Berlioz, Liszt, Wagner, Boulez
    Batshit: Schumann, Scriabin, Ravel

    …regardless of historical truth. Which is inevitably more interesting.

    So What’s your fave bit of Bach? I can’t stop listening to the Wachet Auf cantata. Especially the famous part that happens at 14:40 in this recording. It’s kinda my favorite melody right now. :pacman:

  • The Fender TBX:
    A Cool 2-Band Tone Control

    You can TELL it's Photoshopped! There's no TBX!
    You can TELL it’s Photoshopped! There’s no TBX!

    Thanks again to everyone who chimed in on the “What your favorite mod?” discussion. I got tons of great ideas from your comments.

    Like this one, which I’ve been meaning to explore for ages: the Fender TBX tone control circuit, which appears in several Custom Shop instruments, notably the Clapton signature Strats. Like the G&L PTB circuit I’m so apeshit about, it’s a 2-band passive tone control — but one that sounds very different.

    The PTB is a two-knob circuit that lets you siphon off highs, lows, or both. I’m agog at how well it works with humbuckers — you can get so many cool sounds by rolling off lows on the way to a fuzz, as heard here.

    But TBX (it stand for “treble bass expander”) is a one-knob circuit, tbough that single knob rotates two stacked pots. The control has a center detente. Set here, it’s like a regular tone control, wide-open. Turn it counter-clockwise and highs vanish, per usual. (You could “tune” the roll-off frequency with various capacitors, though I went with the stock .022uF.) But when you rotate clockwise, the absence of lows makes glassy highs erupt.

    The dual pot cut highs or lows.
    The dual pot cut highs or lows.

    Technically, it’s not a boost, but it sure feels like one. Dirk Wacker, my now-colleague at Premier Guitar, dissects the circuit far more capably than I can here. (And he goes way beyond in this subsequent article on TBX mods. Man, I have some catching up to do!) He makes a good case for replacing the stock resistor with another value, but I went with the original 82K to establish a point of reference. I’ll try his mod when I restring, and I’ll update you here.)

    BTW, you need the Fender TBX kit for this project — it uses highly customized pots to work its magic, and a standard stacked pot won’t do. But it’s cheap: You can find the TBX kit, with the pot, hardware, and passive components, online for about $15.

    I put it into the mongrel strat I’ve been using as my digital synth/looping guitar. I’d been using a Stellartone Tone Styler, a cool Vari-Tone variant that switches between multiple capacitors. I dig it, but it’s the old model which clicks, rather than fades, from setting to setting, and it requires a powerful twist of the wrist to go from maximum to minumum, which I do every time I grab an EBow. Since I hadn’t gotten around to replacing it with the smooth-action version, I figured I’d try the TBX.

    And I’m glad I did. It’s a super-easy install, at least to the extent that any job that requires removing both strings and pickguard can be easy.And here’s how it sounds:

    I’m going to keep this one around for awhile. You’re hearing it through an analog rig, obviously, but I want to find out whether that extra shot of highs does anything meaningful when playing digitally. I’d also like to experiment with different cap and resistor values.

    And now I can’t help wondering whether this would sound cool with humbuckers. Anyone have any experience with that?

  • I’m Performing Solo. Yikes.

    joe_solo
    Seriously, dude — where’s my band?

    Anyone have much experience playing solo instrumental guitar gigs?

    Even though I’ve been playing since the Pleistocene, I’ve only performed solo once since I was a teenaged classical guitarist. But I’ll be making the stumble leap this Wednesday, Sept. 11th, when I perform north of San Francisco at the Sleeping Lady Cafe in Fairfax. I’ll be a guest at Teja Gerken’s monthly fingerstyle guitar showcase, performing alternating tunes with Teja and Mark Goldenberg. (Gig details here.)

    Both Teja and Mark are gifted players and composers — check out the evidence here and here. I believe they’ll be playing acoustically, while I’ll be dragging up my whole frickin’ looping/synth rig. Because what could provide better counterpoint to an evening of refined and intelligent fretwork than a goddamned electronic racket?

    Oh — that one solo gig? It too was a multiplayer solo guitar night featuring some astonishing players: Will Bernard, Jim Campilongo, and Buckethead. Will, Jim, and Brian were as amazing as you’d expect. Meanwhile I put everyone to sleep by performing the entire Bach A Minor Lute Suite on steel-string acoustic. (I’m sure the audience was duly impressed by my formidable memorization skills as they nodded off.)

    I’m not repeating that mistake! This time it’ll be fuzz and feedback, with a double side order of ring modulation!  :pity:

    So got any survival tips for performing solo? Any good jokes for during the inevitable laptop crash and reboot?

    If all else fails, I can borrow a trick that the late, lamented Danny Gatton once shared with me in an interview: A lifelong tinker, Gatton built a stompbox designed to blow the power in any club. If he didn’t like how the gig was going, he’d click it on, plunging the venue into darkness and calling it a night. (Or so he claimed.) Hmm — maybe that’ll be the next tonefiend DIY project….

  • What’s Your Favorite Mod? (Here’s Mine.)

    How am me make guitar thing better?
    How am me make guitar thing better?

    What’s your favorite guitar mod? The kind that changes how you play. One you’ve become so accustomed to that you wince when you pick up an axe that lacks it?

    I’ll choose pickup wiring mods as a starting point: During the year that Seymour Duncan sponsored tonefiend.com, I devoted many posts to the under-appreciated wiring schemes I found in the company’s wiring diagram database. Some faves:

    …and of course, the suicidal soldering mission known as the Pagey Project.

    I’ve still got the “advanced” version of the Pagey wiring in my nothing-special beater Les Paul, and I like it so much, I want to fix up the guitar so it feels as nice as it sounds.

    But of all the wiring experiments I tried, my absolute favorite is one that doesn’t appear in the Duncan archives: the so-called “PTB” tone control (for “passive treble and bass”). It’s a cliché to call a neglected idea “ahead of its time,” but in this case, it happens to be true. Being able to roll off lows as well as highs is unbelievably useful when sculpting sounds. It makes me want to run into the nearest Bain Capital Guitar Center, grab players by the collar, and shout, “You need to know about this!” (But I probably won’t, ’cause G.C. customers aren’t accustomed to receiving that sort of personal attention, and I wouldn’t want to freak them out.)

    Allow me to repost last year’s video, demonstrating the circuit in action:

    Over a year later, I remain totally addicted to this circuit, and I recommend it to anyone who doesn’t require a guitar with independent volume controls per pickup. (Everyone, basically.) It seems especially relevant for drop-tuned and 7-string metal players who realize you must sometimes cut a little bass to keep the lowest register tight and articulate. And the circuit is a godsend when used with bass-heavy fuzz pedals (such as vintage-style Fuzz Faces). In fact, I’ve even been building the circuit into the front end of certain loud fuzz pedals for use with guitars lacking this magnificent mod.

    But I remembered something interesting this week when I opened up the Hamer 20th Anniversary guitar used in the video: (more…)

  • Sister Rosetta Tharpe (and the False History of Rock & Roll)

    Sister Rosetta Tharpe
    (and the False History of Rock & Roll)

    NOTE:Nothing controversial about this post — it only involves race, gender, and religion!

    A few decades ago, the standard history of rock and roll went something like this: In the mid 1950s. black R&B and white country music collided. White kids went apeshit. Rock happened.

    That may hold a bit of water as sociological history, in the sense that, yes, white kids got hip to R&B in the ’50s, and the term “rock & roll” was adopted to describe the resulting craze. But as musicological analysis, it’s bullshit.

    Today the knowledgable listener is likelier to realize that all the ingredients of early rock and roll percolated throughout African-American music decades before Elvis. (How can anyone with ears not perceive Louis Jordan’s 1949 recording of “Saturday Night Fish Fry” as a fully realized rock & roll track?)

    Nowhere is “white guy-centric” rock history more apparent than when discussing the legacy of Sister Rosetta Tharpe (1915-1973). How is it that she is perceived as anything other than a genre-defining rock guitar innovator? If you don’t know Tharpe’s astonishing guitar work, check this out (especially the segment that starts around 1:45):

    Watching the footage of Tharpe’s 1964 performance in Manchester, England, you can practically feel her spawning a thousand British rock bands. (And how telling is it that one of her goldtop Les Pauls wound up in the possession of Big Jim Sullivan, the preeminent British session player of the ’60s?)  (more…)

  • Phasers That Stun

    phaser_stun

     

    UPDATE: My Premier Guitar Heptode Virtuoso review is live. Read and listen here.

    I’ve got phase shifters on the brain, especially after encountering a couple of truly stunning ones. I just wrote a review for Premier Guitar of Heptode’s Virtuoso phaser, a superb clone of the old Maestro PS-1A. (I’ll link to the review when it goes live.)

    It took me back to my Pleistocene pre-teen years, when I once spent hours in my local music shop playing an electric nylon-string through a big-ass PS-1A mounted on a music stand. Despite its size, it had few controls — just big colored switches that could have been swiped from one of the era’s cheesy home organs. It sounded glorious to my 12-year-old ears. I’ve never since held such a high opinion of my own playing.

    I haven’t played a PS-1A since then, but the Heptode pedal took me right back. It really is a gorgeous-sounding phaser, and one that vanished soon after the debut of the cheaper, smaller, and awesome-sounding MXR Phase 90. The sound captivated me all over, though I’m not sure if I actually like it more than the Phase 90, or if it just sounds so cool because it’s a less familiar color.

    The plastic switches make it sound better.
    The plastic switches make it sound better.

    I dug out a few other favorite phasers, like the $89 BYOC Phase Royale that usually lives on my analog pedalboard. It’s yet another brilliant DIY kit from BYOC’s Keith Vonderhulls. It’s basically a Phase 90, but with all the cool mods, like mix and resonance controls, plus a six-stage phasing option. (The Phase 90 and the Uni-Vibe are four-stage, while the Maestro is six-stage). It’s a fun build, and an excellent next step for DIYers who have built a few fuzzes and are ready for something a bit more challenging.

    I concluded my little phase-fest by unearthing my old Lovetone Doppelganger, a bitchin’ dual-LFO phaser from the late ’90s. Not to be confused with today’s Lovepedal brand, Lovetone was a British company run by Dan Coggins and Vlad Naslas. They specialized in large-format pedals with an almost absurd number of controls. (Their brilliant slogan — “Big Pedals to Trip Over” — is rivaled only by Zachary Vex’s “Crazy Effects for Rich People.”) I’d flip out when each new Lovetone pedal came in for review at Guitar Player. Even then, they were expensive, usually in the $400-500 range. Now, of course, they’re obscenely rare and valuable. I bought as many review models as I could afford, and to this day I regret not purchasing their Meatball, Wobulator, and Brown Source. I did, however, snag the Big Cheese, Flange with No Name, Ring Stinger, and this guy:

    I haven’t heard the Doppelganger in years, and it was interesting to revisit it. See, while I always loved the ideas behind the Lovetone boxes and was happy to own them, I’d found that I just didn’t tend to use them a lot for gigging and recording. For me, they had tons of cool sounds, but often not quite the right one. But I’ve gotten better at dialing in tones in recent years, and really dug the sounds I got yesterday while making the video. Maybe it just took me 15 years to learn how to wrangle these beasts!

    Anyway, the Doppelganger is now a Museum of Lost Effects inductee, and it’ll be joined soon by its big-box brothers. (more…)

  • It’s Raining Germanium!

    I just bought 500 germanium transistors. Yes, as a matter of fact, I am insane. Why do you ask?
    I just bought 500 germanium transistors.
    (Yes, as a matter of fact, I am insane. Why do you ask?)

    UPDATE: My Dunlop Fuzz Face Mini review is live at Premier Guitar. Audio clips included!

    How and when did it get so frickin’ easy to procure great-sounding germanium transistors?

    I’ve been building stompboxes for four years or so. I used to consume article after article detailing the sheer horror of dealing with germanium. Sure, those old-school transistors sound great, I’d read, and they’re necessary for vintage distortion circuits. But they’re unstable. They’re expensive. They’re hard to find. You have to sort through dozens to find the few good ones. And once you do, you must spend countless hours matching and biasing them for optimal sound.

    I believed everything I read — until I finally admitted to myself that I seldom encountered any of those problems.

    (If you don’t know much about germanium transistors and why they’re cool, here’s my manifesto.)

    I used to buy germanium transistors from Small Bear and other parts sites, and was always happy with the results, even though I had to pay eight or ten bucks per transistor. (Small Bear even does the matching for you, offering sets of transistors suitable for various vintage fuzz circuits.) However, it was a little tough finding NPN (negative-ground) germanium transistors. In fact, Small Bear once rejected my order of a dozen or so NPNs because they were so scarce. (To his credit, Small Bear’s Steve Daniels explained that he restricted sales so that everyone who wanted to build a couple of great DIY fuzzes would have the opportunity.)

    The workaround is to build pesky positive-ground pedals, or jigger with the schematic in order to use PNP (positive-ground) transistors in negative-ground circuits. (This site’s Fiendmaster project is an example of the latter workaround.)

    Then some odd things happened: (more…)
