Hi all. This is my first post. I've read a lot of older posts about this bass and have mixed feelings on the subject. I'm wanting to pull the trigger on the GL MIM Jazz bass but it seems that a lot of people think that the passive pickups are a sound killing issue. I played one a friend just got and loved it, but it was played through a little POS practice amp and can't judge it's true sound by that. I play in a cover band (rock and dunk mostly) and am looking for a deep growl sound for the rock. Will this bass do it or should I keep looking? Thanks for your help.
