TONE VOLUME
The tone volume is controlled using the ‘TONE VOLUME’ control on the back panel. Increase the volume by turning the POT clockwise
and counter-clockwise to decrease the volume. The MASTER volume control does NOT affect the tone volume.
IMPORTANT: Do NOT drive external voltages into the pins as damage to the unit will occur.
