Developed after intensive design collaboration with the legendary guitarist, Eddie handed over his AHoly Grail@ Crybaby - a standard Crybaby customised in the early 90's with a more vocal-like high Q indicator and wider frequency sweep. Eddie=s unique Wah style, which uses mostly the middle range of the pedal=s action, had carved it=s own curve into the pots resistive element, making the middle range even more defined and increased the low end sweep. The clones of the worn-in pot and hand selected inductor give the EVH Wah the same AHoly Grail@ feel and tone. True hardwire bypass, dual blue bypass LEDs and graphics round out this EVH approved Crybaby. Powered by 9 volt battery or AC adaptor (RPC921R).
