Alright guys. I need help. I'm looking for suggestions of a 24 fret Fender Jazz-Style bass as an upgrade from my Yamaha RBX 170 but still relatively inexpensive (400 dollars?) new or used. I've been playing this bass for a long time and have grown very used to it. I now play in a metalcore band and need something more versatile than the RBX but am still looking to play a bass that feels like it. I'm not only looking for a 'metal bass' but something to cover any genre. I've considered buying another RBX and gutting it, adding an onboard EQ, new bridge and actives. Would this be a feasible idea?
