Charlie Christian (and That Pickup)

Despite being obsessed with Charlie Christian for decades, I’ve never played a Gibson ES-150, the guitar he made famous. I’ve never even messed with a “Charlie Christian pickup,” even though it’s been a fairly common retrofit ever since the late Danny Gatton installed one in his Tele’s neck position. But I’ve always wondered: Could the C.C. pickup work in styles other than jazz? How would it sound in the bridge position? (The ES-150 had only a neck pickup.) And most of all, how would it sound with nasty fuzz?

Lollar Pickups helped me answer those questions with a loaner of three humbucker-sized Charlie Christian pickups. These differ cosmetically from the originals, lacking the cumbersome mounting hardware and the ornamental top plate. But they’re convincing sound-alikes, with similar magnets, wires, windings, blades, and modest output. (Their DC resistance is just under 3k ohms). Here’s what I discovered!

Clearly, it’s not a pickup for every rock guitarist (though it’s perfect for a swing-era jazz sound). Still, I found its non-jazz sounds strange and compelling, and I can definitely imagine using them in the studio. What do you think?

While making comparisons, I spend hours reacquainting myself with Charlie’s recordings, of which there are only a few dozen. His career was absurdly brief — it was less than three years from his first recordings with Benny Goodman through his death from tuberculosis (and probably other bad stuff) at age 25. But that was long enough to forever alter the guitar’s history.

Just How Heavy Can a U-Bass Get?

I've had this cool Kala U-Bass for a few years. (I did a video on it back when I got it.) I've used it on a few things, especially when I want a sort of Latin-flavored Ampeg Baby Bass sound. (That solidbody upright from the 1960s is largely forgotten, except in Latin dance bands, where it's considered the classic bass.)

But I've recently started rehearsing with a new band featuring my pals Jane Wiedlin, Pietro Straccia, and Dawn Richardson. And for perversity's sake, I decided to try using this little uke bass as the sole bass in band. (And Dawn hits those drums pretty hard!)

The above video demos some sounds I concocted using Fractal's AX8, the "light" pedalboard version of Axe-FX II, the company's flagship amp/effect modeler. I'm quite encouraged by the results! AX8 has no power amp, so I've been plugging into one or both of the Fishman LoudBoxes I use for my solo looping gigs. And if we play somewhere with good monitoring, I can just bring the uke bass and a small shoulder bag. Total lazy old guy gig!

The sonic missions were pretty simple: Amp up the lows. Nix as much of the ugly piezo pickup quack as possible. Concoct enough patches to make a nice, interesting palette for a set. There's still more to do, especially in terms of modifying my technique for the instrument. I'm still not quite comfy to the super-short scale. Also, I'm too accustomed to resting my picking hand on the body or bridge, and the piezo loves to amplify those thumping and scraping sounds.

But overall, I'm encouraged. Plus it's just sick fun. :)

The One Weird Thing About Gold Foil Pickups

Okay, the funky gold foil pickups found in cheapo Japanese and American gutiars in the 1950s and ’60s are popular again. And trend slut that I am, I’m smitten with them. But they do this one really weird thing ….

It has to do with the capacitive relationship between the guitar volume knob, pickups, and downstream pedals and amps. If you don’t use your guitar’s volume knob as an expressive device, this behavior probably doesn’t matter. But if you do, this is potentially a big deal, one worth considering before purchasing a pair of gold foils.

I first realized this as I was preparing my Gore Pedals demo for the NAMM show. Many of my pedal designs depend on the ability to alter tones from the guitar — it’s how I get away with using relatively few knobs. It’s the quality you hear in the first minute of my Cult pedal demo:

You just can’t do that with gold foils. Apparently, the rubber magnets in gold foil have a different capacitive relationship with downstream gear, relative to conventional alnico- and ceramic-magnet pickups. Some of the peaky, high-resonance sound you get when rolling back the volume knob on a guitar with gold foils are pretty cool, and I can certainly imagine using them. But I definitely have to modify my technique when using gold foils.

I recently reviewed one of the bitchin’ new Supro guitars for Premier Guitar. Their pickups are based on a different historic gold foil model, but they exhibit the exact behavior demoed in my first video above. After writing that review I spoke with Ken Calvet of Roadhouse Pickups, who created the excellent-sounding Valco-style gold foils for Supro. He acknowledged the unusual volume knob behavior and attributed it to the rubber magnets used in historically accurate gold foils.

My first video above demonstrates this property using a capacitance-dependent vintage-style Fuzz Face. Not only do you encounter the same thing with many non-buffered (i.e., cool) fuzzes and boosters, but also when plugging directly into an overdriven amp. You can’t summon clean sounds from a dirty amp via the guitar volume knob the way you can with most conventional passive pickups.

But despite all of that, I’m still crazy for the Lollar Gold Foils in my DIY Resistocaster:

Has anyone else noticed this quirky characteristic?
