Electro Harmonix Doctor Q - Vintage

 Layout based on the old version from the 70s. Note that this one is really picky about op amp selection so be prepared for some socketing...



Monkee Music Satan Distortion

 I admit that I did a layout for this soleily based on the name...😏

This is one those really cheap 80s distortions that sounds harsh, compressed and trebly. But it might be worth modding towards something decent? The clippers can be subbed for LEDs for some headroom, both 47pF caps can be inreased to shave off some high end. Also the Tone control and the 10nF cap next to it can be adjusted.Oh, and don't forget to use an expensive Burr Brown IC for the op amp...

Schematic is avaiable HERE.
