Yerasov Gamma DS-1 Distortion
Old Yerasov Gamma series distortion. Box totally looks like a Boss rip off, but the insides are not.

Don’t bother asking for a schematic. One doesn’t exist. This layout is based on FSB thread on the subject…. (yes, you’ll need to log in to see it) — The thread at FSB got wind under its wings after this layout, so the questionable values are finally confirmed. Here’s the final layout with updated values … Read more
There you go John. We’ll never have enough bass designs… This one is basically a Rat for bass. Thanks to John, this one is now verified. Which also means that the LM7 and FC10 should be safe to build.
Ok. As the original layout for this circuit was originally drawn from a bad schematic and altered later, i thought it would be a good idea to redraw this from a trusted (Dirk Hendrik’s) schematic with original buffering in tact. I also removed the old one from the archives… As this Rat adaptation shares the … Read more
The orginal unit uses two 9V batteries and electronic swithing. I removed the latter, but left the supply voltage wanting the 18V. With this, i also left the (possibly) destructive polarity protection method in tact. For the supply, one can use two batteries or add a small daughter board to pump the standard 9V voltage … Read more
The first in a line from the MXR Custom Badass design team, the MXR Custom Badass ’78 Distortion is a factory-modded pedal that roars with huge amp stack tones and old school tube amp-like distortion. We took a classic distortion circuit and hot-rodded it to the next level for over-the-top soaring leads and rich, saturated … Read more
Yup. Most of you who know me know that i’ve had more than enough trouble with JFET biasing on some fixed drain resistor designs… This one also has the input cap and pulldown resistor at the input. Already verified by me. I found the best gain to be with drains at ~5V, but now you … Read more
This one seems to be quite rare thing. You can score one for >$200 at ebay. It is Morley’s vision of the MXR Dist+/DOD OD250, with some noticeable changes. Might be worth a build… Picture from Effects database.
Here’s something cool. The design reminds me of something else a lot – i think some of you may want to take the diodes on a switch with red 3mm LEDs 🙂 Original unit has NEC C157C metal can IC in it, but NEC’s own cross reference guide says that this particular IC has been … Read more
