Way Huge Green Rhino MK II
Here is a layout for the Way Huge Green Rhino MKII overdrive. I would like to thank Ciaran Haslett for drawing a schematic by reverse engineering his own pedal.

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 that’s been simplified. And secondly, I included 2 trimmers to help set the bias of the J201s (you’re welcome, Cody). With 3 pots … Read more
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, and the 3PDT footswitch is board mounted. I would suggest using small profile jacks for this like these, or just … Read more
CmatMods Butah
Here is a slightly modified version of the Marshall Bluesbreaker that is supposed to sound very nice.
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. Schematics, sound clips, and more info can be found on the ROG site.
Crazy Tube Circuits Ziggy Overdrive
Here’s a cool MOSFET-based overdrive from Crazy Tube Circuits. 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 sounds like a Plexi. It was traced over on FSB (link here) and I’ve laid it out for … Read more
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 where an extra diode could be for asymmetrical clipping, so I’ve included room for the … Read more
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 the input. It’s laid out for board mounted pots and will fit nice in a 1590B.
Maxon OD-F1 Fire Blade Overdrive Effector
YATS from ’94, recycled by Maxon. Asym clippers and slightly lower rolloff frequency for the high pass. Should be a decent alternative for the standard TS.
