Got an Electro - Harmonix echo / chorus / vib pedal in with no effects output. Needed a schematic to see where the signals went, so emailed them. Within a couple of hours, I had an email back, with pdf's of the two versions of the circuit attached. How's that for good service ? Well done E - H !!
What an unexpected pleasure to find a company that still takes customer care and tech support seriously :-)
