Return: Use this jack to receive the output of your effects device or another amplifier’s send or direct output. This path sends the signal to the power amp and is post EQ and Master Volume. At this point you are accessing only the power (output) section of the amplifier.

Slave: The Slave out is a 100-ohm compensated signal that is in parallel with the speaker output. It contains the full complement of preamp and power amp characteristics of your amp. Use this output to send your signal to a power amplifier connected to additional speaker cabinets for a louder version of your amp.

Slave Level: This controls the level of the output from your Slave out. If slaving to an effects unit in a stereo amp rig, use the unit’s input sensitivity LED lights as a gauge to set the slave level. Use this control to avoid overloading the input of your slave amp or effects unit.

Speakers: This is where you plug in your speaker cabinets.

Impedance: Select the proper impedance to match your speaker load. Our combos and cabinets are normally wired for 8 ohms unless otherwise stated.

Getting Started:

Initial Setup: Start with the Drive channel, then set up the Rhythm channel.

Drive Channel

Select the Drive channel by pulling the Master control out. Set the Master Volume at approximately 9 o’clock.

Next, use the Drive control.

We recommend starting at around 10 o’clock.

As you rotate the knob clockwise, listen to your signal until it begins to distort. The higher the setting, the more distortion you will add to your signal.

Dial the right amount of distortion until you are satisfied with your overdrive.

Go back and turn up the Master Volume to add girth to the overall tone. Notice how the amp sustains a note longer when the master is turned up.

Find your sweet spot using the Drive and Master controls. This will be a good reference for your Drive channel.

Rhythm Channel

Select the Rhythm channel by pushing the Master control in.

Next, use the Rhythm control

Rotate clockwise until the volume of the Rhythm channel is at a good level relative to the volume of the Drive channel.

Try pulling the Rhythm/Brite control to add treble, shimmer and brightness (see Pull “Brite”).
