So, I'm in the market for a new amp and I'm feeling torn between the many offerings out there. I'm placing a limit of $500 on my new (or used!) head. I dont necessarily need something 'versatile'; I basically just need something with a good "clean" tone and some ridiculous overdrive that I can dial in to my liking (i'd rather not have to depend on a pedal for my dirty tone). I play in a classic rock band currently, but I also play alot of chordal solo jazz material and I want to use the same amp for both situations. I'd like to get an all-tube head, but I can deal with a hybrid setup if it saves me on weight and complexity. For example, I can get a Peavey AlphaBASS all-tube head for $300 or I can get Peavey TB Raxx tube preamp and a Peavey DPC 750 for about 400. I play medium size venues so I need plenty of power, but i would like to maintain portability since I do alot of loading and unloading by myself. I'm currently playing through an 8 ohm Peavey TVX115, and my bass is a TBC AP500M. I dont have to stick with Peavey, but it's treated me well so far and suggestions from the wise bass monks of talkbass?
