I figured out my problem with my old combo, and figured out a perfect way to frankenstein it into a head. 120 watts, 4 ohms. I was thinking about cabs, and came across a few, and I thought so far this one would be good: http://www.musiciansfriend.com/product/Yamaha-BBT410S-4-x-10-Bass-Speaker-Cabinet?sku=601412 250 watts RMS handling, 4 ohm. If you can think of anything in that price range ($300 max) please let me know. I do know about Avatar, but I think the gap of 120 watts and 1000 is awfully large, and I'd doubt I'd be able to find them at Guitar Center.
