Im a guitar player who is buying a bass rig to play for a band and i just dont know that much about the gear. Ive played ampeg stuff, been in bands with ampeg users and was not impressed at all with their cabs. The head I was looking to buy was the SWR SM500, or the the SVT-3. Ive played through the Goliath III, Mesa PH215, Ampeg 410HLF, 410HE, and 810E with the SM500 (havnt tried the SVT-3) and when i played it through the Ampeg cabs the sound was extremely dull, not nearly as fat and puncy as the SWR. Like i said i am a guitar player, but i still know a good bass tone when i hear one. I just want something thats in between the Hi-Fi and Lo-Fi sound. Actually im looking for the bass tone that sounds kind of pathetic by itself, but with a full band contrasts the music perfectly, here is a Link to the music if anyone is interested . Ill be playing a All parts J bass with duncan PU's through a BBE, MXR Phase 90 (sometimes), and a Boss Bass OD. Another thing, I work at a guitar center so thats why I have chosen Ampeg/SWR, because thats mainly what we carry. Anyways any help or advice from people who actuallyknow the gear would be great. Also, besides power handling and price, what are the major differences between the Goliath II 4x10 and Goliath III?
