I am working on buying my first head. Right now I have an Ampeg BSE-115T(8Ohm) powered by an Altec Lansing power amp and BBE 383 preamp. It sounds fine for practice and playing with my guitar player but it's not the sound I'm going for. I really liked the tone I was getting out of my friends Hartke 3500. So I was considering picking one up. But I really like the Ampeg tone. Several bass players I know use and love their svt3 pro amps and I like dirty sound they get with it. Those are out of my price range. So I was considering the B-2R head. Will the b-2r and my 115 get me a good ampeg tone? What other heads should I be looking at in the sub $500 range? Down the road I will be adding a 2x10 or 4x10 so having some expandability would be good too. Thanks for any help Nick PS: very informative message board you have here!
