Hi, I'm in the market for a new amp to complement my Bassman 100. Right now, I'm looking at this Carvin stack package (link). Now, either way, I would get the two cabs. I really like the 18 and I've heard good things about the 4x10. The price is especially compelling. Anyways, I can't figure out whether to just get the head that's in this package or find something else. I'm thinking about building a component head, and to that end I just bought a 1/3 octave eq. the power amp would be relatively straightforward (1000 watts+), but I have no idea what sort of preamp to get. What's good, and in the $100-$300 range? It's really hard to find information on what's available for bass. Another option is to get a package head. Of course, I will have to sell the EQ, but that's not a big deal. The two I really like right now are both by Fender, the Bassman 1200 or 300 I really like the tubes in the 300, are there any other decent tube heads for a comparable price? ($1,100). My last option is to get the head that comes with that package. Is it good enough (obviously it powers the amp), but in terms of quality and options? it seems kind of small and weak for the cabs it powers, and I really like tubes. Is there a preamp I can run thru on an effects loop or something? I know I'm lazy, but I really appreciate any help I can get with this stuff. It's a big purchase, and I want to make sure I don't screw it up any more than necessary. Thanks!
