Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Garnet Sessionman G250FTR is a 250-watt Canadian professional head incorporating built-in footswitchable tremolo and reverb, aimed at touring session players. This was among the largest and most feature-rich amplifiers in Garnet's catalog, reflecting the company's ambition to compete with American and British high-power designs in the early 1970s. The Sessionman name communicated a professional studio-and-stage identity.
