I've always used big, giant, ugly amps. I've never had a problem with them. It made me feel like a bass player to have a giant stack sitting next to me. It was my comfort blanket. However, my back isn't as strong as it once was, I'm starting to hate stairs, and a recent problem with my Peavey tube amp that left it dead in the water has me a bit concerned. I don't want to be left without an amp at a gig, for instance. For that reason, I'm trying to revamp my rig a little bit, and add a backup head. The Yorkville 410B that I'm playing through now just isn't getting it done for me. I've decided to go the custom cab route, and ordered a set of BFM Jack 12 plans. I'm planning to build at least two of those so I can go modular - big gigs get more cabs, small gigs and practice get fewer. I'm also planning to keep my Peavey VB-2. I love that amp, and I don't think I could part with it. What I want is one of those new micro amps that I could stick in a pocket in my gig bag and have a backup head with me just in case the tubes let go during a show. I've tried searching, but my search-fu is poor. If anyone can point me in the direction of any comparo-threads, or just outright recommend something for me, I would certainly appreciate it. I play typical bar-band covers and a bit of classic rock. I'd prefer buying used to save the bucks. Price should ideally be under $4-500 or so, but could swing a little bit more if necessary. What say you, TB?
