So I've got an Orange Terror Bass 500w amp head - I love love love the preamp, but boy is that power amp brutal. With the volume knob just barely at 1, the amp is already way louder than I'd like for just playing by myself, especially when I start diving the preamp in pursuit of a nice overdriven sound. So here's what I'm thinking: I'll replace the master volume pot with something of the same value, but a multi-turn instead of a single turn. The idea is that I'll get finer control on the low end of the knob but ultimately have the same range. Any reason this wouldn't work? Is there any kind of minimum power for class D amps or anything like that?
