My brother just bought a bass two weeks ago (I've been playing for 3 years) and he happens to have money to burn. So basically, I'm getting a free amp out of him. He bought an ampeg ba-115 combo. (100 watts, 15" + tweeter). I like it a lot except for the loud hiss from the tweeter (eq does not help it).So we're gonna take it back and exchange it for something else. I recently came upon a small some of cash, so we can go about $100 higher than what the Ampeg cost ($450) I need something that will eventually be able to handle small gigs. I play all styles-- latin, jazz, rock n' roll, metal. Every once in awhile i might tune to CGCF, but mostly i stay in standard. My bass is a 4-string Squier P (go ahead, laugh now), his is a 4-string MIM Fender Jazz (unfortunately, he's a lefty, so I can't steal it). The only feature that I really require is a compressor or some good EQ presets. What's my best bet around $550, new?
