Besides the above, Red Bear MK120 if you can find one. Designed to have plenty of low end even at low volumes, works great for bass.
Mesa/Boogie D-180 (channel 1 is for guitar, channel 2 is for bass).I remember that I tried my bass in the shop through a Blackstar HT Stage 100 Head and Marshall Cab, and it sounded bloody good! So much so that I'm thinking about saving up for one sooner or later. Does anyone else know of any guitar amps that work well with bass?
The Dual Showman was the default bass amp for a short period of time between the little bitty Fifties bass amps and things like the SVT and the Acoustic 360. You'll pry mine from my cold dead hands.
And a Marshall Superlead works well too!Marshall Superbasses and some of the other early models (JTM 45/100, JTM 100) if you're into that tone.
Great for electric guitar, acoustic guitar, and bass. Wish I still had mine.I think a Roland JC120 is good if you are not turning it up loud or at a small gig. Very bright tone but eq it down and it works quite well.
