Hey guys, first post I play bass in a thrash metal band and I need a bass rig to gig in medium sized venues but to keep the price to a minimum as i'm having to fork out for my driving lessons in thee weeks when I turn 17 I have been giging with friends rigs for the past 6 months all trying to sway me to get the brand they back. Ive been looking absolutely everywhere and I really cant decide on what I want. Does anyone have any suggestions on a rig for really max £500 It needs to be fairly loud but not extremely so. any help would be much appreciated Dan
