I've got an Ibanez GR that I can't seem to get a good sound from. The best way to describe it is" "flat." I've tried rounds and flats on it, but I can't dial in a sound that I like. It is the only bass I have that has active pups and it is also the only one that doesn't "growl" or "sing". It has a great feel and very low action, so it should be a pleasure to play, if I could only get it to somehow "grow a pair." Thanks for any advice.
