Developed after intensive design collaboration with the legendary guitarist, Eddie handed over his - Holy 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 - Holy 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 (ECB003).
