I have a 1970 1200s sunn amp, most of the sunns I have seen posted are have 4 knobs on the unit. The amp I have has the four knobs plus a rate,depth,and reverb knob. Question can this unit be used for both guitar and bass, where can i find a manual for the unit, in what would be the cost of a working amp.
Also, I have a sunn 4/12 guitar cabinet, is there manual and what would the worth be of the unit. Can the sunn head above be used with the speaker cabinet.
