Quarantine Update

Made a video. Watch it here:

EQD Black Ash

Hope everyone's having a safe and healthy Fuzz Friday. Found out the Black Ash had been traced and figured I'd draw up a layout. I figured it was a pretty straight Tone Bender Mk II clone, and it is with a simple tone control tacked on just before the volume pot. Was slightly surprised that it uses all silicon transistors. The resistors in the originals are old school carbon comps for the mojo. Here's the schematic for reference. You can probably get away with 4.7k and 47k resistors instead of the 4.6k and 46k resistors listed. Also alternatives to the 2N3903 would be 2N2222a, 2N2369, etc. Shoot for 100-150 hFE.

If you want a fabricated PCB to build on, check out the Earthbender in the store.

JSA Ampldrive

Like many, I find myself working from home for the foreseeable future due to the COVID-19 pandemic. Most of my time so far has been trying to accomplish my day job in sweatpants and help my wife do hers (aka, kid wrangling), and I haven't had much time to build anything. But yesterday I did carve some time out to create today's layout. Shout out and thanks to Simon from JSA Effect Pedals for sharing some of his creations with me. Check him out on Instagram for build notes on this particular circuit. It's a pretty simple drive and should go together pretty quickly if you have all the parts on hand. And if you don't, he's got some notes on alternatives. Enjoy and stay well folks. Thinking of you all.

BearFoot Fx Pink Purple Fuzz

Sneaky Fuzz Friday you probably didn't see coming! And on Valentine's Day too boot. See? I still love you guys. Here's Bjorn's Pink Purple Fuzz, a hybrid JFET, silicon, and germanium transistor fuzz. Schematic and discussion on FSB here. And don't forget about the sale going on over on the store. "Val20" at checkout gets you 20% off your whole order!

Note: I'm a bit rusty. I laid the whole circuit out before realizing the Nature pot wasn't centered, and still isn't on the perf side. So if you're building on perf, and board mounting that pot, you'll just need to angle it a little to fit to the drill template.

2020 Update

Update time! Check out the video:

Ibanez MT10 Mostortion

It's New Years Eve and time for the last layout of 2019 and I'm pretty sure it's the 800th on the blog! So here's the Mostortion. Why is it called that? The CA3260E opamp at it's core is MOSFET based. Unfortunately, this chip has been discontinued, so building a straight clone may be a little difficult, but a regular dual opamp like a JRC4558 or TL072 will work just fine as well. It's pretty similar to a TS10, just with a MOSFET chip and 3-band EQ, which is pretty handy. Schematic and more info here. Should be able to squeeze it into a 1590B.

Way Huge Conquistador

Happy Fuzz Friday, everyone! Last fuzz of 2019. Here's an interesting fuzz circuit from Way Huge based on the Tone Bender Mk. III. It uses PNP silicon transistors, but is a negative ground effect. Schematic available here.
