I vote start over. I would look into the Hartke LH1000 head and the Hydrive 410 cab. Great setup, LOUD! and you can get one for a little over $1000 brand new... less if you look used. Also if you can get a good deal on a 410 cab, HelloMusic.com will have the GenzBenz Shuttle 9.0 head for under $500 (that is a deal on this head). Lots of options out there. now a guitar rig CAN sound sweet as a bass rig. Case in point: Peavey Triple X head. I tried this beast by itself on top of a ampeg 410 and it sounded great. Clean channel was surprisingly deep and punchy, and the lead channel was straight out Lemmy!
