The YSR-1 Custom Reverb is Traynor's late-1960s guitar head with built-in effects. Two channels, each with two inputs, a 12AX7A stage and its own volume, mix through a second 12AX7A into shared bass and treble controls. A 12AX7A drives a spring reverb with its own recovery stage, reverb gain and footswitch, and another runs a tremolo with speed, intensity and footswitch. A 12AX7A long-tail inverter drives two fixed-bias 6CA7s from a silicon bridge.
