ewan ko, pero the way i see, Dime's tone is very stable due to the choice of using the solid state rather the tube, and the mids are really pulled down, i think the sig amp that were made was a derived version of a Randall that he used. about the pedal he uses, men i think he doesn't even use his sig pedal MXR Dime Dist. though hearing it can make you realize it could o it could not sound as what Dime's tone is. that pedal isn't high gain at all, it's mid scooped, really really scooped.
Shameless plug ++> Sorry OT, hehe, TS if you're looking for a MXR Dime Dist, i'm letting mine go, PM me, hahah!
