hey guys have a question. when i'm playing a live show for my band I use the Ibanez PD7 Tone Lok pedal for heavy bass overdrive/distortion. but I have this annoying feedback problem. because I play pretty articulate riffs on bass and whenever I pause for a moment there's that loud squeal. is it the pedal or my bass (Yamaha rbx a5) or my bass head(fender bxr)? if its either of these, is there a pedal out there that can help remedy this problem without loosing much of my tone?
