The Valve Master is a 100-watt, two-channel Carvin tube amp from 1994 with four fixed-bias EL34 or 5881 output tubes. Relay-switched channels each have their own bass, mid, treble, volume and presence control; Channel 2 adds a drive control and diode clipping between its gain stages. A tube-driven spring reverb, an effects loop, a 12AX7 long-tail phase inverter, a 4/2-tube output switch and a cabinet-voiced line out complete it.
