I have a 6 string ibanez SR886. When amplified it produces a metallic clank sound. I have isolated it to the pickups--when I tap them with my finger the clank sound comes through. The sound can even be heard when the bass is not plugged in. Does anyone know what could be the cause of this problem? Are they too hot? Would lowering the pickups help? Are they just bad pickups? Only the softest touch will prevent the sound on the lower strings, and I like to have the option to dig in. I don't think this model was made for very long, could this be a pretty common problem?
