Basic Operation
The ¼” mono instrument cable that leaves your guitarʼs jack plugs into the Twin Tube Classicʼs jack marked “Input.” The cable that exits from the “Output” jack on the Twin Tube Classic goes to the next effect in the signal chain, or to the amplifier.
When first activating the Twin Tube Classic, start with the Rhythm Channel Volume and Gain control knobs in the full
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 Classic.
Experiment with different Volume and Gain settings. Some of the coolest tones are achieved with a little discovery. Because of the Twin Tube Classicʼs 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.
