I use one these (with an insert cable) as an exp pedal for my DL-4, Vortex, Digitech 2120. I'm pretty sure it will also work as a feedback pedal for the EDP. I suppose you could even use it as a volume pedal on the outputs of your effects boxes. I haven't tried that though. http://www.americanmusical.com/cgi-bin/SGIN0101.EXE?UID=2001040502084329&T1=PRL+PVP14L&UREQA=3&UREQB=5&FNM=00 John ===== John Tidwell __________________________________________________ Do You Yahoo!?
