Here is a fantastic Diaz Tremodillo . These boutique pedals were all hand made/wired by Cesar, (SRV’s tech) it has a lush and dreamy bell-like tremolo effect similar to a 60’s Fender Blackface. This pedal appears to date to the late 90's ,most were a blue colour with grey being a more rare finish, there is some minor wear on the housing but the pedal functions as it should . No box
