I bought one just a short time ago. It is a very nice pedal. Even though I haven't played it that much, so far I seem to like it a bit more with single-coils than humbuckers. With humbuckers it sounds a bit 'fuzzy' on the low e-string (PRS Cu22 through an EL-84 amp), but that may just be the character of the pedal. What is your preferences for this pedal? Do you think it works better with one or the other?
