Electro Harmonix Small Stone V3

 

There was a an incorrect value in the factory schematic. It is now corrected and the layout is verified by slammer88.



Electro Harmonix Pulsar

 A modified layout for the old EHX Pulsar which is infamous for its LFO ticking bleedtrough. There is two mods that hopefully can solve it. First, an op amp input buffer and second  the more common mod; separating the power with a small value resistor between the amplifier and the LFO section. LFO section also have its own power filter cap.
