This is a combo power amp to be used for playing live with modeling pedals. I used it with the Line 6 X3 Live (Going up for sale in another thread). This amp has no tone stack or pre-amp section, it is meant to be a colorless amp that will reproduce what you would hear when listening to your modeled tones through cans, but louder.
It does have simple EQ controls but those are meant for eq'ing for a room to get you back to flat, rather than tailoring your sound.
Pretty much meant for modeling pedals, although it is great if you just want a pure clean tone from a guitar as well.
This is a guitar amp, not really for bass.
No longer available in this configuration(2x12), these used to retail for $475.
