[sdiy] guitar effects (small stone Electro Harmonix)vs synthesizers

[Harry Bissell]

It would depend on where you use the effect. On an output, the synth better be about
line level (maybe 1V) or your mixer, amp, speakers, ears... are toast.

On a single internal output (before final attenuation..) anything goes. Probably
+/- 14V is quite possible. Most modulars do NOT limit levels, they assume you want
to do what (and ~know~ what) you are doing.

Sorry, I meant to say ±5V, not 5V peak to peak! That does make 10V peak 
to peak. IIRC then RMS is -3 dB from peak to peak, but don't quote me on 
it. Anyways, Ken Stone talks about a scaling factor of 20 between synth 
and guitar effect levels.
