Basic Operation

The ¼" mono instrument cable that leaves your guitar's jack plugs into the Twin

Tube Blue's jack marked "Input." The cable that exits from the "Output" jack on

the Twin Tube Blue goes to the next effect in the signal chain, or to the amplifier.

When first activating the Twin Tube Blue, start with the Rhythm Channel Volume

and Gain control knobs in the full counter-clockwise position. Then, start rotating

the knobs clockwise until the desired volume level and overdrive are achieved.

Next, with the Lead Channel Volume and Gain control knobs in the full counter-

clockwise position, depress the Channel Selector switch. This mutes the Rhythm

Channel and activates the Lead Channel. As with the Rhythm Channel, start

rotating the knobs clockwise until the desired volume level and distortion are

achieved, relative to the Rhythm Channel and to the bypassed sound of the Twin

Tube Blue.

Experiment with different Volume and Gain settings. Some of the coolest tones

are achieved with a little discovery. Because of the Twin Tube Blue's incredible

amount of gain and distortion in the Lead Channel, be aware that extreme settings

can result in uncontrollable feedback. And, as always, musicians and audience

members are best advised to use ear protection when exposed to loud volume.

Here are some sample settings to get your started:
