CONTROLS
VOLUME: Sets the output volume.
DRIVE: Controls the amount of overdrive.
FOCUS: Controls how easily the circuit distorts as well as adjusting overall EQ. Turning CCW gives less distortion and a mellow effect, turning CW gives a slight treble boost and earlier distortion. Good starting point is 11 o’clock.
ELECTRICAL SPECIFICATION
