Live Looping

Loopocalypse Day 16 (of 17): “Luxardo”

Inspired by the most sublime thing you can drop into a cocktail. Or maybe that and the cocktail.

The guitar is a random collection of Fender Strat parts with Duncan lipstick tube pickups. They sound a zillion times better than modern Danelectro pickups. (Plus I boycott Dano on principle because their parent company is a major supporter of homophobic far-right legislation.)

Here’s an explanation of my live looping rig.

Ultimate Lipstick-Tube Guitar (with experimental tone control & onboard overdrive)

Okay, it’s not the ultimate lipstick-tube guitar for everybody, but it probably is for me. It’s my third lipstick-tube pickup experiment — and definitely my favorite.

You may have heard some of these parts before: I used the neck for all my Mongrel Strat projects, and the Strat-sized Seymour Duncan pickups appeared in my previous lipstick-tube experiments. (I love Duncan’s lipstick-tubes. To my ear, they sound way better than the ones in new-school Danelectros.) The new body is Warmoth’s Hybrid Tele model, in purple with butterfly stickers. It’s très macho. (Better not use if for gigs in Indiana and Arkansas.)

My previous lipstick tube experiments used a MIM Strat body, but I wanted something a little more distinctive, and with a built-in battery compartment (because nothing is a bigger pain than changing batteries in a traditional Strat control cavity). Also, I like how the design evokes both Strat and Tele, since the guitar has three-Strat sized pickups and a whammy, but is wired more like a Tele.

About that wiring: The 3-way pickup selector chooses neck, bridge or both pickups, like on a Tele. Meanwhile, a SPDT switch toggles the middle pickup on and off regardless of the pickup selector, so you get six settings: neck, bridge, neck + bridge, neck + middle, bridge + middle, and all at once. It’s a pragmatic variation on “Nashville Tele” wiring with a switch rather than a pot. That means you can’t dial in varying amounts of middle pickup—it’s all or nothing. But on the plus side, I can jump instantly to an out-of-phase sound from any pickup-selector setting, and it freed up space for the other weird crap I put in this guitar. (Yo, electrical engineers: Don’t bother telling me that combined-pickup settings aren’t really out-of-phase True, they’re not out-of-phase electronically, but they are acoustically, and the distinctive “hollow” sound of combined settings is precisely the result of phase cancellation from two pickups at different positions.)

The weirdest detail is what I call a “cap-fade” tone control. It’s an idea I speculated about back in January, and to which many of you contributed cool perspectives. I pretty much followed the scheme in the original diagram:

cap-fade tone control

The idea again: Instead of sending varying amounts of signal to ground via a tone cap, the pot here fades between a small-value cap (which defines the minimum cut when the control is engaged) and a larger one (defining the frequency of the maximum cut). In other words, instead of sending varying amounts of signal to ground, this circuit always sends everything above the cutoff frequency to ground, with the pot determining the frequency.

The Lipstick Lab
New Experiments with Old Pickups

Do you ever get an idea that you just know is going to work out brilliantly? And then discover you were totally wrong?

That’s how it was when I finally reassembled my generic Mexican Strat with Duncan lipstick tube pickups. After I recorded a demoing of it here almost two years ago, the guitar lay in pieces alongside my workbench. I’d stare at decapitated body, feeling guilty and dreaming of all the fantastic mods I’d attempt when I finally got around to reanimating it. I had various ideas for the tone control: Maybe a two-band PTB control? Nope—totally underwhelming results. Perhaps a two-in-one TBX? Meh—even less interesting. I drew a blank, and the guitar wound up with a disappointingly normal tone circuit.

But I did discover some cool twists along the way. Details after the video:

My flatwound string addiction is only getting worse, but this is the first time I’ve combined flats and lipstick tubes. (Has anyone done that since the ’50s?) The results were fascinating. As happens when you put flats on an electric 12-string, you encounter a paradoxical increase in highs, despite the darker-toned bass strings. (Maybe it’s because the treble strings ring truer with less phase-canceling interference from roundwound bass strings.) As you can hear, this instrument doesn’t lack for zing.

The opposite, actually — treble notes explode from the instrument, often more than you’d like. I experimented with various action and pickup height adjustments, but no matter how I set things, it was difficult preventing certain notes from shrieking. The only solution was to play the damn guitar for a few hours and grow accustomed to the touch.

The Ultimate Mongrel Strat? (with Obsessive/Compulsive Tone Control!)

Not for everybody: The sickest mongrel strat yet.

Okay, I lied.

In the previous installment of our ongoing mongrel strat series, I experimented with a version of Gibson’s oddball Vari-Tone circuit. I said it was too fussy and complex, and that I wanted to experiment with a simplified version.

So naturally, I built a “parts” Strat with a Vari-Tone twice as complicated as the original — a configuration I’ve dubbed the “Obsessive/Compulsive Tone Control.” I also deployed some of my favorite quirks and wiring tricks from previous strat experiments, plus a few new hardware discoveries. Result: a weird-ass guitar that only a geek could love a cool, one-of-a-kind instrument.

Check out the demo. Post-mortem after.

Meet Mongrel Strat #1

Three "mismatched" Duncan pickups in an off-the-rack Mexican Strat. (Left to right: Lipstick Tube for Strat, Alnico II Pro Staggered, Twang Banger)

As previously threatened, here’s the first installment in a series on unusual Strat pickup combinations, inspired by a big box of Duncan pickups and a couple of prewired “BYOP” pickguards. I tried a couple of meh combinations that I didn’t like enough to record, but this third experiment seemed worth sharing. Dig this odd combo: Lipstick Tube neck. Alnico II Pro middle. Twang Banger bridge. Comments and post mortem after the clip. Have a listen!
