I bought what looks like a brand new bass IQ from a pawn shop for $50, anyway buy it, take it home, plug it in(using a new 9volt) and bypass works great, but when i step on it, all i here is a low level distortion. When i crank up my amp enough, i can hear the effect working within the distortion, but i can't get rid of it. also i have to hit the strings hard for it to push through to put out sound, with the threshold control up. Has anyone had these problems, or know of a way to fix it??? Is my pedal fryed???
