I've had the Jekyll and Hyde overdrive/ distortion pedal and I've never had any problems with it before. I've got it hooked up to a fender Frontman 15g amp. For the past few days, I've been getting obnoxiously loud feedback when i hit an open G string or the 15th fret on my B and high E strings. This is really annoying when I'm soloing and really need a way to get rid of or at least reduce this feedback. If it helps, I've got a Squire Stratocaster HSS (2 singe coils and a bridge humbucker).
