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?

Phasers That 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.

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:

The WRONG Way to Use a Talk Box

Any talk box fans out there?

Whew. Didn’t think so. I mean, doesn’t everybody hate those godforsaken things? Wasn’t it all downhill after “Tell Me Something Good?”

But did you know that the “talking guitar” has a rather exalted history four decades pre-Frampton Comes Alive? Check out this performance by Alvino Rey, the steel guitar genius who pioneered the technique.

I am TOTALLY going to have nightmares about Stringy for the next 10 years!

Rey worked his magic in tandem with his vocalist wife. She supposedly stood behind a curtain with a mic attached to her throat, the output of which modulated the guitar signal. (That’s what online sources say, though it sounds a bit fishy to me.) A similar technique — or perhaps the same one — was known as the Solovox. In this case, a small loudspeaker attached to the singer’s throat, “playing” the music through the vocalist’s mouth. More amazing/horrifying evidence:

That’s the basic principle behind the rock-era talk boxes, though they rely on a plastic tube inserted into the mouth rather than a mic pressed to the neck. The first commercially available model was Kustom’s The Bag from 1969, “immortalized” on Steppenwolf Live. The Heil Talk Box — the version of the effect most of us know and loath — debuted in 1973. Dunlop is still making them.

But I have a perverse affection for the Rocktron Banshee. It’s incredibly loud. It’s actually a small amp, quite capable of driving a speaker cab, with a blunt-force distortion tone. That extra power is useful for my preferred way of using a Talk Box:

How about you guys? Anyone have anything good to say about the talk box?

Example 2: high gain, medium tone

Pedal A = BYOC clone
Pedal B = Klon Centaur

Example 3: low gain, medium tone

Pedal A = Klon Centaur
Pedal B = BYOC clone

Example 4: medium gain, bright tone

Pedal A = Klon Centaur
Pedal B = BYOC clone

Example 5: medium gain, dark tone

Pedal A = Klon Centaur

NEW CONTEST: Klon vs. Screamer
Identify the Audio Clips and Win!

Left: Klon Centaur #309, worth over $2,000.
Right: BYOC Overdrive 2, a $95 Tube Screamer clone.

It’s hardly a new idea: YouTube is full of Klon vs. Screamer comparison videos.

But this one is different.

Using the same “reasonably scientific” techniques deployed in my recent germanium fuzz survey, I’ve created a blind listening test that removes as many variables as possible from the equation.

The video details the testing procedures. But basically, the A/B recordings are identical save for the use of one pedal or the other. The rival pedals are Klon Centaur #309 (the unit reviewed in Guitar Player back in the ’90s) and a new BYOC Overdrive 2, a DIY Tube Screamer clone kit with extra knobs and pots to provide the most popular boutique mods.

This Klon would fetch north of $2,000 on EBay. You can order the Overdrive 2 online for $95.

Now, these two pedals are NOT identical circuits. (The key differences are covered in the video.) But they share the same topology and sonic character. It’s not an apples and oranges comparison — more like two apples of distinct but related varieties.

For the video I dialed in five different sounds from across the Klon’s range, and then tried to duplicate them with the BYOC Screamer clone. You’ll hear the same material ten times, like so:

Example 1: medium gain, medium tone

Pedal A =
Pedal B =

Example 2: high gain, medium tone

Pedal A =
Pedal B =

Example 3: low gain, medium tone

Pedal A =
Pedal B =

Example 4: medium gain, bright tone

Pedal A =
Pedal B =

Example 5: medium gain, dark tone

Pedal A =
Pedal B =

To compete, just fill in the blanks and copy your answers into the comments thread below.

The pedals might not appear in the same order for each pair of audio clips. Other than that, there are no sneaky tricks. (For example, you really do hear two different pedals for every example.)

 

The first three contestants to submit perfect scores before Tuesday, July 23rd, 2013, will each win fabulous prizes one of my hand-built stompboxes. On that date I’ll post the answers and announce the winners here, assuming there are some. You can still test your ears after that by watching this video and not peeking at the answers — but sorry, no more prizes.

Only one entry per person. Anyone caught circumventing this rule via multiple identities may be subject to global ridicule.

I’ll hold off on any sonic observations till I post the correct answers next week.

Good luck, and may the best ears win some gnarly stompbox.

Fuzz Detective Appendix 1.0

D’oh! I omitted a circuit from the Fuzz Detective video. It’s the germanium version of the Shin-Ei Companion Fuzz FY-2. So here’s a brief Fuzz Detective Appendix.

The silicon version of the FY-2 is a cult item, a nasty little thing best known for its appearance on Jesus and Mary Chain’s Psychocandy album. The germanium version (which I didn’t even know existed until reader Bear pointed it out!) is a very different beast. Most notably, it lacks the silicon version’s signature midrange scoop, delivering a thicker, fatter sound.

As noted in the video, I replaced the stock B50K gain pot with a B5K. (The overall range of tones is pretty much the same, but this way, all the variations aren’t crammed into 10% of the knob’s range.) Construction details and testing procedures are the same as they were for the 12 Fuzz Detective pedals.

Fuzz Detective:
The Case of the 12 Germanium Fuzzes

As threatened, the Fuzz Detective video:

WHAT: Twelve germanium fuzz circuits compared and analyzed. These represent the sounds of almost every fuzz pedal introduced between 1962 and 1968.

WHY: A tool to help players identify the circuits most relevant to their musical needs. This isn’t about particular brands of pedals, but the circuits they employ. If you hear something you like, you can either do as I did and build a clone from the schematic, or buy one based on that particular design. (The relative merits of rival clones is another story.) Of course, if you’re rich and you desire an ancient pedal that probably doesn’t sound as good as a new clone, you can always purchase a vintage original. 😉

HOW: I tried to establish a “level playing field” by removing as many sonic variables as possible. I used the same signal chain, the same guitars, the same musical material, etc. (Tech details below.)

WHO:

  1. Maestro FZ-1 Fuzz Tone
  2. Sola Tone Bender Mk 1
  3. Hornby-Skewes Zonk Machine
  4. Sola Tone Bender “Mk 1.5” (similar to Vox Tone Benders)
  5. Dallas-Arbiter Fuzz Face
  6. WEM Pep Box Rush
  7. Sola Tone Bender Mk II (same as Marshall Supafuzz)
  8. Mosrite Fuzzrite (germanium version)
  9. Orpheum Fuzz (germanium version)
  10. Selmer Buzz Tone
  11. Sola Tone Bender Mk III (same as Park Fuzz Sound, Carlsbro Fuzz)
  12. Baldwin-Burns Buzzaround.

WHEN: Like, now, man!

Fuzz Detective: The Plot Thickens!

Man, I’m glad I announced my intentions about this project! Thanks to your links and suggestions, the “Fuzz Detective” project has grown vastly more ambitious. I need a few more days to make my test recordings are assemble the results, but I believe this will be the most complete and “scientific” audio comparison of 1960s fuzz circuits yet attempted. I’m posting this update to share my current plans — and solicit last-minute suggestions for improving them. —Joe

Wanker’s dozen: twelve germanium fuzz pedals will finally compete on a level playing field.

I’ve been a busy little solder monkey! Dig my new pedals:

1. Maestro Fuzz Tone FZ-1 clone
2. Sola Tone Bender “Mk I” clone
3. Sola Tone Bender “Mk 1.5” clone (near-twins: Vox Distortion Booster, Italian Vox Tone Benders)
4. Dallas-Arbiter Fuzz Face clone (very similar to Tone Bender Mk 1.5)
5. Hornby-Skewes Zonk Machine clone (near-twin: Tone Bender Mk 1)
6. Sola Tone Bender “Mk II” clone (near-twin: Marshall Supafuzz)
7. Orpheum Fuzz clone
8. WEM Pep Box Rush clone
9. Mosrite Fuzzrite clone (germanium version)
10. Selmer Buzz-Tone clone
11. Sola Tone Bender Mk III (“3-knob”) clone
12. Baldwin-Burns Buzzaround clone

About the Fuzz Detective project:

I’m attempting to create a comprehensive comparative sound library of germanium-transistor fuzz pedal circuits.

There’s no shortage of audio clips and demo videos featuring the great stompboxes of the ’60s and their modern clones. Yet it’s difficult to make qualitative comparisons between circuits because there are so many other variables at play. Who performed the examples? Using what gear? Were the examples recorded in a pro studio or on a mobile phone? Are the pedals ’60s originals or modern clones? What’s the condition of the transistors? And so on.

This isn’t about, say, deciding who makes the best Fuzz Face clone. The focus is the circuits themselves. The Fuzz Detective project aims to “level the playing field” by removing as many variables as possible.

Next Week on Fuzz Detective!

UPDATE: Based on cool info supplied by YOU, dear readers, I’m expanding the scope of this piece. I’m furiously wiring up clones of some very rare models, and I can promise many cool and interesting surprises. Thanks, guys! :beer:

Okay, now that we’ve all gotten that silly “reading” stuff out of our systems with Book Week, it’s time to get back to the real focus of this blog: nasty, filthy fuzz pedals.

Last time we were on the subject, we looked at the original version of Dallas-Arbiter Fuzz Face, and included Mitchell “super-freq” Hudson’s beautiful DIY instructions.

Those posts generated many interesting comments — plus some misinformation on my part. For example, I said that the original Fuzz Face circuit is a close cousin to the Tone Bender Mk I, which would mean, for example, that known Mk 1 user Mick Ronson was essentially using a Fuzz Face between his Les Paul and his Marshall. But subsequent listening and reading makes me believe I was wrong. So I figured it was time to play fuzz detective and sort the facts from the other stuff.

First, I made clones of all the early commercial fuzzes. I’ll be posting a compare-and-contrast video in the coming days. (The audio forensics will be quite incriminating.) Here’s the lineup:

The usual suspects. (Incriminating audio/video evidence to be posted soon!)

I’ve also re-read the experts, and man, even my most trusted sources contradict each other right and left, especially when it comes to those darn Tone Benders. While I have absolutely no inside dope on what actually transpired, I think David from D*A*M Stompboxes offers the most convincing Tone Bender chronology, which you can read here.

Anyway, here’s my best guess about how the early fuzz years unfolded:
