Re: new EDP question

Can you try the new EDP with a regular, passive volume pedal with a mono 
cable instead of TRS expression pedals?  Maybe the newer EDPs are less 
tolerant?  Kim's Echoplex pages recommend the Boss FV-50L pedal while 
sounding a little surprised that the EV-5  worked:

To build or modify a pedal for EDP feedback, 
says to use a 20k ohm or greater pot between tip and sleeve.

For your old unit, these links might explain heat-induced weirdness.  If 
it is pre-1997 vintage you might need to clip an IC pin 
and for pre-mid-1998 models, the power supply's voltage regulator can be 
updated to run much cooler according to
