I recently purchased the beige Gibson Oberheim echoplex
Anyone working with either EDP, echoloop or mobius should read and listen to Andre's Echoplex analysis pages: http://www.altruistmusic.com/EDP/
Plenty to learn from on those pages... read a couple song analysis every week and integrate the technique he's writing about. You'll be playing in Santa Cruz soon enough (or Seattle, Paris, Cologne, Berlin, Rome, Antarctica, etc...).
