I found this somewhere in thread devoted to another pedal. After half a decade...

A write up and review of the Harmony Synth, not as good as the actual schematic but still interesting.

It may be a good idea to remove that "schematic" tag in the thread title.

Got one of these in for repair so here's some gut shots of this illusive unit, although I doubt anyone will be tracing this any time soon!

Thanks! This one has been on my wish list for quite some time!

However;
Could you make the top view again? Preferably outside in daylight without shadow and fully covering the PCB (the right side is missing ;-) )

Here's what I have. Not much. I guess that it's pretty safe to assume there's no more than this floating online. That is, The other stuff on the ADA Harmony Synth that came from ADA depot are some mechanical drawings and a description/instruction of a test fixture for selection of the SAD's. No schems, no layouts, nothing electronic. Therefore I guess the 2 photo's above are the best that has shown up in quite some time.

:oops:

I don't think the weather is going to permit me to take photos outside so hopefully Raf's suffices.

Plus, I won't be able to take more pics right now... The pedal is somewhere in UK :mrgreen:
