I am having one of those yearly tone issues... (I'm sure that we all know what I'm going through here) I am looking at changing my whole amp set up. Right now I have a SWR sm500 into a Goliath III (4x10). I mainly play a Thumb bolt-on 4-string...and I have a Fender Jazz back up. I play in a Rock group with just 1 guitar, 1 bass...and so I really want a loud, full, thick, ballsy sound. Most people say that we sound good and 'complete' for a 4 piece, but I think that my tone can improve some. I have been working a lot with overdrive lately, I have a SansAmp DI that I have been using full time. Here are some options I have been looking at doing: * keep my current set up, add a 1x15 to the bottom * Getting a Mesa Bass 400+ with ampeg 8x10 * Getting some tube preamp - with a crown power amp (or some other solid state amp to push different chains of tube preamps) any suggestions?
