The Ultrabass BX1200 combo, I didn't really have an amp that could handle a low B (playing through a guitar practice amp at the time) so when I ordered my 5 string I included the ultrabass so I could have a bass amp to play through. Since then I've used this little sucker in the following ways:
+ As a practice amp
+ As a makeshift PA system when my band's was on the fritz
+ As a keyboard amp for that two weeks I decided to play keys

()
- As a vocal monitor at a show (as of that show, the front panel shocks you when the volume is turned past 6)
- As a D.I. (colored like nobody's business even while bypassing the eqs)
- As a bass amp in band practice when I was without a cab (blown voice coil, or something)
- As a coffee table (no room to put stuff on the top)
+ As a fun machine to mess around with (It makes weird sounds like all the electrical problems and speaker mishaps it's undergone, I don't plug anything by my old ibanez gio into it for fear of it blowing up my active basses

)
So I've used and abused this guy, but I still think that I didn't overuse it enough to cause all the problems it has. shoulda gotten a kickback instead... but now that I have the thing, eh, I can't bring myself to get rid of it, it's seen too much!
