I just purchased an EGDM from another forum member, specifically for use with my DST30 (AC30 clone). Loving it, from the 1st note sounded. Excellent range, from a light Tweedy grind to heavy saturation reminiscent of Lennon's 'destroy the preamp' Revolution tone. Very dynamic, as of course one would expect. Still just getting acquainted with it.
EGDM gets infrequent mention here, of late, so I thought I'd give it a plug. Some comments Donner had posted regarding the EGDM controls were helpful.
