I want an amp with one knob and one switch. The knob will be "Volume". It should go from silent to bar gig loud. The switch will be for "Mute". The circuitry will in no other significant way manipulate or alter the signal the amp receives. You guys have any leads for that? As far as ohms and all that, if you can identify an amp that meets my requirements, I'll get the other gear that matches it for use.
