This is it for, now. Covid restrictions were lifted here today so I'm going to take a break and try to live a normal life for a while ;-). But here is a project of the 70s version of EHX Clone Theory which should keep you occupied for a while. An onboard voltage doubler is included followed by a 15v voltage regulator for the required power supply. The only addon in the audio path compared to the vintage units is a booster stage and volume trim before the output to cure the slight volume drop when the circuit is engaged.
Schematic is avaiable HERE.
