Ive been doing gigs for a while and want to invest in a good amp setup. (Was thinkin a cab & head?) The only problem is if im gonna spend alot of money on something, i want it to be worth it. Cause im only 16 i figure will be using it for awhile. Ive been looking at Ampeg and Gallien-Krueger cause they have a good rep and all. If it helps, i play a Fender p bass and a Warwick Corvette 6. My style is grunge & heavy metal. Would appreciate the advice & any suggestions.
