Martin 112T - Channel 1 preset

Close · 78/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Martin 112T is the tremolo version of the 112, a valve combo C.F. Martin sold alongside its early-1960s electric guitars. It was built in Toledo, Ohio, by Rowe Industries, the maker of DeArmond pickups, as a rebadged DeArmond R15T. Two channels with separate volumes share a tone control, and three 12AX7s handle the preamp, phase inverter and tremolo (rate, depth, footswitch), driving two cathode-biased 6V6GTs on a 5Y3GT for about 12 watts.
