A dual overdrive based on the classic grey spec DOD 250. The schematic didn’t come from the original EQD pedal. David has recreated the circuit on his website (Perf & PCB Effects Layouts). You can find his original and verified layout here.
This is the 400th layout on the blog. Kinda hard to believe I’ve drawn up that many. O_O The cool dudes from Akron cooked up the Grey Channel, a dual overdrive based on the classic grey spec DOD 250. The 250/Distortion + circuit is one of my favorites and it turns out it’s one of EQD’s … Read more
Madbean’s great new project based on Earthquaker Devices Sea Machine. Original infos available here. 17/07/2016 Layout updated! Changed 33n cap to 3n3 and 10k resistor from PT2399’s pin 14 back to 1K.
Here’s a fun distortion from EarthQuaker. Tonally, it’s based on a cranked Sunn Model T amp and uses 2, 386 chips. It cleans up nicely with the guitar’s volume, so a good mod would be adding a pot before the input. John K did this and used a reverse log 1M pot.
Original infos: The Acapulco Gold is a dirt-simple power amp distortion device that’s based on the vibe of a cranked Sunn Model T. You know what is awesome? Simplicity. One button, one knob. How loud would you like it? Just move the knob. This is the spirit of rock and roll. Quit turning knobs and … Read more
Here’s a cool variation of the Vox Repeat Percussion tremolo from EQD. It adds some extra controls to the original circuit for more versatility and control. I had a hard time tracking down a schematic for this one and ended up just tracing the vero layout from the Tagboard Effects blog. So here you go … Read more
Info about the original: The Talons is an extremely versatile high gain overdrive that serves up the full range of gain from transparent boost to heavy saturation, and all points in between. Unlike all our other overdrives, the Talons was not designed to emulate any specific sound or era. The presence control gives you a … Read more
Hi guys! Alex here and I’m very excited to join the tagboardeffects squad. Thanks to Mark and Miro for the opportunity, and thanks to Travis, Zach and Javi for joining along. My first contribution to the main site is a great guitar synthesizer from EarthQuaker Devices. I would like to thank Njokki for reverse-engineering his … Read more
The Bit Commander is an synth/octave effect that’s all analog. It creates square wave synth tones across 4 octaves (2 up, 2 down) and it’s capable of creating a wide range of sounds. The octave down effect is generated from the ICs, while the octave up comes from the 4024 and transformer (kind of like … Read more
The Ghost Echo is a nice little reverb unit, and uses the Belton BTDR-2H-L digital reverb module, as well as a PT2399. I’m not going to lie, this layout gave me some issues (at one point it made DIYLC crash). Even had to use a jumper (which annoys the heck out of me, as you … Read more
