King Rat dylan159
A King Rat using a dual op-amp. It replaces the JFET output buffer with the spare op-amp stage. Its another schematic from this thread on Freestomboxes.org. This looked like a really smart idea, I had to try it. There is…

UBE Screamer v2
Here is an updated post for the UBE Screamer v2. The UBE Screamer was invented by the smart guys over at RunOffGroove.com, tireless purveyors of all things stomp box from the early days of the hobby. The UBE Screamer was…
Peach Fuzz Clone
I have wanted to try the Frantone Peach Fuzz for a long time. The circuit uses one of my favorite chips the LM386. Not only does it use the 386 it uses two in series. Frantone is one of the…
Summon Fuzz a bigger muff
This is Mic Tester’s 21st Century Big Muff. Its the standard big at it’s heart but updated. It uses an op-amp for the input and output stages, a James tone stack, and adds an interesting gain control to the clipping…
DS-1 Robert Keeley mods
I rehoused a few new circuits into some Boss enclosures last year. Boss Buzzbender Boss DRV Boss Muff I was left with some DS-1 PCBs. I have been rehousing these into 125B enclosures! It might seem a little crazy butI…
PWM Build
I built another PWM. This is a a crazy noise maker. Almost more of a synth than guitar pedal. It has a great distortion sound but the output is extremely compressed, which makes it hard to use a band situation.…
Scuzz Box v1.1
This is a second version of the Distort-O-Matic XI from stompboxology. You can read about the first versions here, and here. Distort-o-matic XI is described as a distortion box with an aggressive tone control. In more concrete terms it’s a…
Distort-o-Matic XI demo
This is an audio demo of the Distort-o-matic XI from Stompboxology. Check out my build page for a schematic and images of the finished project.
The Crank by Mark Hammer
This is interesting variation on the Tube Screamer style diode clipping. Read more about it at Mark Hammers site here: In a nutshell the goal seems to be less distortion. More of a booster to overdrive effect. I’d say…
UBE Screamer 4069
I wanted to do something a little more artful as a box. The Joy Division’s Unknown Pleasures has a very iconic image. I don’t know what the secret sauce of this image is but it’s very compelling. From what I…
Smash Drive Aron Nelson
Smash Drive is a DIY community project by Aron Nelson, who runs the DIYStomboxes.com forum. Smash Drive is a overdrive/distortion built from the LM386. Its simple and easy to work with. you’ll find the 386 in many guitar circuits. its…
PWM demo
This is a demo of Tim Escobedo’s PWM. see my build page for more info about this circuit: Here is another song demo where the PWM was used on one track in the mix.
