Here’s how to set the type of amp that’s connected to the OUTPUT (A/MONO, B) jacks. This lets you calibrate the sound to give you the optimal sound for that amp.
- Turn off the power (unplug the cable from the INPUT jack).
- Set the type knob to “TWEED”.
Turn the [AMBIENCE], [LEVEL] and [GAIN] knobs all the way counterclockwise, and turn the [BASS], [MIDDLE] and [TREBLE] knobs all the way clockwise.
While holding down the pedal switch, turn on the power by inserting a plug into the INPUT jack.
After the CHECK indicator lights up green, it cycles between blinking orange three times and staying lit.
Use the type knob and the [AMBIENCE] knob to select the type of amp that’s connected.
