Any K150 or K250 head can be used for bass even if its the effects model as the two preamp channels are the same reguardless.
My testing has shown that the K250 effects equiped models do put about 12 watts less power due to the power supply carrying the load of the added effects circiutry.The K150 effect models how ever have a added item in the power supply called a choke, and my K150 with the first stage effects pakage( minus fuzz and wa, but with reverb/trem/vibrato)will output every drop of its 75 watts rms rated power!
