Send Jack: Connect to the input of your effects via ¼” shielded instrument cable.

Return Jack: Connect to the output of your effects via ¼” shielded instrument cable.

Footswitch

Switches between Clean and Lead channels. Plugging in the footswitch over-rides the front 
panel Channel switch. 

Bias adjustments

Left bias adjustment: Controls the bias of the two left-most output tubes, V1 and V2 (See 

tube chart on pg. 12). The setting is locked in place by the outer locking nut. To make an 
adjustment, slightly loosen the outer locking nut.

Right bias adjustment: Controls the bias of the two right-most output tubes, V3 and V4 (See 

tube chart on pg. 12). The setting is locked in place by the outer locking nut. To make an 
adjustment, slightly loosen the outer locking nut.

Note: The 4 output tubes work in pairs; the left bias control adjust the bias voltage for V1 and V2, 

while the right control adjusts the bias voltage for V3 and V4. While the output tubes can only be 

adjusted in pairs, a test jack is provided for each individual tube to provide more accurate bias 

monitoring (e.g. trying to find a faulty tube).

Test jacks: For use with standard multimeter probes.

Black common probe jack: Plug in common meter probe here.

V1 red probe jack: Plug in probe to monitor V1 (See Tube Chart on pg. 12)  output tube bias 
voltage.

V2 red probe jack: Plug in probe to monitor V2 (See Tube Chart on pg. 12)  output tube bias 

voltage.

V3 red probe jack: Plug in probe to monitor V3 (See Tube Chart on pg. 12)  output tube bias 
voltage.

V4 red probe jack: Plug in probe to monitor V4 (See Tube Chart on pg. 12)  output tube bias 

voltage.
