Electro Harmonix Black Finger Compressor/Sustainer

Here is a layout for the older version of EH Black Finger.

I've used Pedalgrinder slightly modified schematic on page 3.
Some suggested high gain some low gain transistors.
Should test them both.


... and a version with LM13700 instead of CA3080

Thanks Mark.
I've also drawn a 13700 version.
I didn't add it to the main page cause the schematic should be verified but I'm not 100% sure.
If any "good soul" will verify it I'll move it.
