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.

Kitschcaster: An Experimental Fender/Gretsch Hybrid

Kitschcaster front

I just completed my third DIY guitar experiment using Warmoth parts. This one is a wacky Fender/Gretsch hybrid with a semi-acoustic Fender Starcaster body, a reverse, angled Strat neck, and various Gretsch-like elements, including TV Jones Filter’Tron pickups, a Bigsby/Vibramate vibrato, and a vulgar silver-sparkle finish — a tribute to the Gretsch Silver Jet, and the basis for this new guitar’s name: Kitschcaster.

Mind you, it sounds nothing like a Starcaster. I ordered the body (which Warmoth calls the Mooncaster) in warm-toned korina, and the neck is mahogany. (Fender used bright-sounding maple for the original necks and bodies.) True to form, the Gretsch-style humbuckers provide a percussive, “plinky” attack quite distinct from PAF-style pickups. The Bigsby assembly also nudges things further from Fenderland. But I always dug the Starcaster’s offset semi-acoustic body, and I thought it would make a nice platform for my latest platypus.

As before, I’m 100% delighted with Warmoth’s work. The finish is flawless (correction: was flawless till I dinged it), and everything fit together beautifully. The only hurdle came when installing the wiring. I failed to take into account the body’s thinness, and I didn’t have enough room to accommodate all the big push/pull and dual-concentric pots I’d planned to deploy. The comic highlight of the build came when I somehow managed to force a standard-sized pickup selector switch into the narrow lower horn. I disconnected a wire while doing so, and then found myself completely incapable of removing the switch. I took it to repair genius Gary Brawer, whose first comment was, “How did you get this in here? And more important, why?” But he managed to free the trapped part, and then he installed a cunning little access cover. Go, Gary!

Yes, the neck is silver too. Gary Brawer added the pickup selector access cover.

I’m especially besotted with Warmoth’s “Clapton” profile necks, which I’ve used in all three of my builds. They have a pronounced V shape that feels so comfy in my left hand, and provides relief for my left thumb joint, where, sadly, I’m feeling my first tentative twinges of arthritis. It’s a trip having three radically different guitars with identical neck profiles. I dig the sleek, comfy body as well, and I love its ability to generate musically coherent feedback.

Anyway, consider this a work in progress. I’m still fussing with the tone circuit. (If I can find suitably sized rotary switches, I want to try a sort of “double Vartitone,” with separate treble-cut and bass-cut dials. If it works out as as planned, I’ll do another post on it.) I’ll also probably jigger with the built-in distortion, taking off some of the treble. Like my Bigsby equipped Les Paul, the Kitschcaster can have overly aggressive highs. Something about the combination of the Bigsby hardware and flatwound strings makes certain notes come screaming out of the amp. Both guitars benefit from a carefully controlled touch.

But even now, I’m really stoked about this fun, cheesy-cool instrument.
