(Apologies for the wall of text). So I don't know if this is stupid, but I'm hoping to find an amp that can work with my bass and my guitars. I've played bass for a few months now, but am a long-time guitarist... right now, all I have is a DI box and headphone amp, so I'm hoping to find a good compromise amp, but I don't have much space or cash to spare. Here are the instruments I want to use: 2003 (I think) MusicMan SUB - 34" scale, four string, passive (recently acquired here on TB). 2007 G&L ASAT Bluesboy - 25.5" scale, set up like an old Tele Custom: ashtray-style bridge, G&L MFD single coil in the bridge, Seymour Duncan SH59 humbucker in the neck, tuned E standard and strung with EB Power Slinky strings (11-48) 1994 Jackson Stealth HX - string-through-body hardtail with three humbuckers, all the same crappish stock Jackson pups; tuned like a baritone B-E-A-D-F#-B with EB Not Even Slinky strings (12-56) I play a wide variety of stuff, though my real love is for metal (mostly sludge, stoner, doom, etc.; stuff with lots of fuzz and bottom). Sonic inspiration includes Sabbath, Sleep, Kyuss, Electric Wizard, but also more traditional metal stuff. I'm looking for verstaility in sound, though... and I'm not stuck on tube sounds (I rarely play that territory where the natural tube distortion is important... it's usually just clean or just dirty). The amp would be mostly for recording and for rehearsal/jam contexts... I don't have a regular band and don't play out really. Finally, I'm looking to spend less than a grand, preferably less than $700. So... am I crazy to think there is something worthwhile that fits all these conditions, or does someone have a brilliant suggestion? A Bassman seems like an obvious possibility, and I've looked a little at the Ampeg portaflex stuff. TL;DR: Has anybody done guitar-through-a-bass amp with success? What about bass-through-a-guitar amp (seems less feasible)? What amp(s) will work?
