Grab & GoGo Delay/Overdrive
Here's a cool little dual effect designed by Allesz over on FSB. I actually laid this out a long time ago, but couldn't wrap my head around the switching with the buffer. I've learned a lot since then...

Cornish G-2
Happy Fuzz Friday, everyone! As promised, here's my layout for the Pete Cornish G-2. The circuit is essentially a Big Muff (with a few different component values) with a simplified tone stack and input...

Cornish SS-2
With the G-2 fresh in our minds, I thought I'd draw up the SS-2 as well. This is set up for a 125B like the G-2 due to the footswitch board. The circuit itself is like an MXR Distortion + with a tone...

Blackout Effectors Mantra Overdrive
Here's a great sounding overdrive from Blackout Effectors. It features a 2-band EQ and the standard drive and volume controls. The topology of the circuit is reminiscent of the classic Big Muff, (input...

Fuzz Jade
Happy Fuzz Friday, everyone. Today's layout is a cool variation of the Fuzz Face circuit, but with the addition of a Big Muff tone stack and a gain recovery stage. There's also a Mud pot that starves...

Soft-Latch Relay Switching
Switching an effect on and off can be as simple or as complicated as you can make it. 3PDTs are pretty much the standard these days for true-bypass switching. However most of the 3PDT footswitches I've...

Keeley Katana
The Katana is a highly regarded clean boost pedal that can give a nice clean boost or push your tube amp into breakup. The circuit itself is fairly simple, but achieves extra headroom thanks to the...

D*A*M Ezekiel 25:17
Here's a non-Fuzz Face/Tone Bender offering from D*A*M for Fuzz Friday. It's designed for bass, but sound great on guitar as well. It uses one half of a dual op amp to blend in clean signal, and the...

Emerson Customs Paramount
This is Emerson's second offering. Essentially it's an Electra Distortion without the clipping diodes and it's pretty similar to the EM Drive. It adds a tone control that pans between 2 capacitors at...

ProTone Dead Horse Overdrive
I actually own one of these from the Dead Pony run, and the other night when I'd run out of solder I traced it. It's essentially a TS-808 clone with a couple of very minor changes. There was a jumper...

Valve Wizard Flanger
Mixing it up and doing Flanger Friday this week. Got a request for this circuit designed by Valve Wizard. It's unique in that it uses 2, PT2399 delay chips paired with an LFO. It features a buffered...

Crazy Tubes Ziggy Overdrive
Here's a cool MOSFET-based overdrive from Crazy Tubes. Apparently it's based on a Neve console input channel stacked 3 times. With the gain down it sounds a bit like an AC30, and with it cranked it...

Run Off Groove Big Daddy/Grace
Here are two great sounding, yet simple circuits from Run Off Groove. The Big Daddy uses a JFET gain stage to push a 386 chip, while the Grace uses a JFET buffer in front of the 386 for added sparkle....

BearFoot FX Arctic White Fuzz
Fuzz Friday is once again upon us, so here's the BearFoot FX (BJFE) Arctic White Fuzz. It's probably based on Tim Escobedo's JFET variations of the Fuzz Face, but with a lot modification. It's set up...

Ibanez TS808 Tube Screamer - 1590A
I've had a couple requests for a 1590A friendly Tube Screamer, and lately I've really been enjoying laying out 1590A boards, so here it is. Since there's 3 potentiometers, you'll need to use 9mm pots,...

Fairfield Barbershop - 1590A
Continuing on with my 1590A kick, here's one for the Barbershop Overdrive from Fairfield Circuitry. I've modified a few things: first, the polarity protection of the original is a bit excessive, so...

Electro Harmonix Big Muff - 1590a
Let's wrap up this 1590a week with one of the mightiest fuzzes of all time–the Big Muff. For this one, I've labeled all the components to correspond with the component names on Kit Rae schematics, so...

Four Step Atari Punk Console
I thought I'd mix things up a little this week and post some synth circuits people might be interested in. To start things out, here's a modified version of the classic Atari Punk Console. This has a...

Devil's Triangle Drone
Here's a synth circuit from Paul in the Lab (schematic and sound samples can be found over there). I've laid it out for board mounted pots with the board vertically in the enclosure. See the drilling...

Galactic Fissure
I thought I'd close out Synth week with a fuzz designed specifically for synths. (Fuzz Friday waits for no man!) This one is pretty straight forward and I don't have much to say about it. Schematic can...
