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?

Meet the Resistocaster!

Here’s a new guitar I put together using Warmoth parts and Lollar Gold Foil pickups.

Around the time I started assembling the Resistocaster, I reviewed the cool new Supro Westbury — another guitar with gold-foil pickups — for Premier Guitar. It was an interesting juxtaposition, because the Lollar pickups are cloned from the models in vintage Teisco guitars from Japan, while the nouveau Supro pickups are based on the gold foils made in the ’50s and ’60s by Chicago-based Valco and used in several of the brands the company produced.

While the two sets don’t sound identical, they have much in common. Both provide full-frequency tones, with warm, cushy bass and open-sounding highs. Like vintage lipstick tube pickups, they have an attractively “hollow” character that always reminds me of an acoustic guitar. Gold foils are gorgeous for clean sounds, while overdriven tones are big and buttery, albeit it rather loose-sounding. (Though adding a bass-cut circuit to this guitar let me dial in tighter sounds.)

Another odd property: With almost all pickups, pulling back the guitar’s level cleans up tones on overdriven amps and dynamically responsive distortion pedals. (That behavior is pretty much the entire premise of my Cult pedal demo.)

But with gold foils, that just doesn’t work! As you lower the guitar volume when playing through distortion-producing gear, tones don’t clean up — they get a little quieter, then sputter out in the pot’s lower range. This isn’t intrinsically a good or bad thing, but as a player who tries to exploit the tonal shifts produced by varied guitar output, I was startled by this property.

At NAMM, I mentioned this behavior to Ken Calvet of Roadhouse Pickups, who created the Valco-style gold foils for the new Supros. He nodded in acknowledgement, and said it was due to the idiosyncrasies of the rubber magnets used in gold foils. (I probably wouldn’t understand the science even if he’d had time to explain it to me.)

But while it took me a while to get comfortable with the gold foils’ unusual dynamic behavior, I needed zero time to fall in love with their warm, character-rich tones. (This, by the way, is the same set of gold foils I recently demoed in my alternative Strat pickups video.

I love how this guitar turned out, and I expect to use it a lot this year. 🙂

Ten Unusual Strat Pickups Tested

I should have been out buying nice presents for you all. Instead I sat around inhaling solder fumes. When the smoke cleared (mostly, anyway) I’d tested ten unusual Strat pickups in the same poor guitar.

Tested pickups sets:

• Jason Lollar Gold Foils
• Lindy Fralin Big Singles
• Seymour Duncan Antiquity II Mini-Humbuckers
• Jason Lollar Staple/P-90 set
• Allparts Gold Foils

Verdicts? I dig them all, and not just ’cause I’m too polite/chicken to say otherwise.

I love the Lollar Gold Foils so much I’m assembling a new parts guitar to surround them. I’m going to keep the Fralin Big Singles in the demo Strat, at least till the next Mongrel Strat Project. I’m going to try putting the mini-humbuckers in a “parts” Tele at some point. I originally reviewed the Lollar P-90 set for Premier Guitar (where I evaluated them the “right” way: in a Gibson guitar), so they go back to manufacturer, though I’d sure like to own a set someday. Meanwhile, the Allparts set isn’t in the same league as its high-end competitors, but at a mere $30 per pickup, it costs about 1/4 the price of its expensive rivals. You could definitely do a lot of lo-fi damage with a pair of these surprisingly solid-sounding pickups!

This article joins the long list of experiments in the Mongrel Strat Project archive.

And how about you? Have you but stuffing any pickups into places where they don’t belong? Maybe that’s why Santa left you sucky presents this year.
