I have a GK410 Neo cab 8ohms and am looking for a cheap head to use with it at rehearsal. Found an ampeg b2r cheap that a guy needs to sell. Good combo??? I play in a 2guitar hard rock band. Would I be able to push that head enough to compete with the guitars? I run the Sheehan pedal or an mxr m80 as a preamp. What does everybody think?
