3. Setup and Connections
Follow these steps to set up your amplifier:
- Placement: Place the amplifier on a stable, level surface. Utilize the tilt-back legs for improved sound projection if desired. Ensure sufficient space around the amplifier for ventilation.
- Power Connection: Connect the supplied AC power cord to the amplifier's AC inlet and then to a grounded electrical outlet. Ensure the amplifier's power switch is in the OFF position before connecting.
- Instrument Connection: Connect your guitar to either the "INPUT 1" or "INPUT 2" jack on the desired channel (Normal or Vibrato) using a high-quality instrument cable. Input 1 typically offers higher sensitivity.
- Footswitch Connection: Connect the two-button footswitch to the "FOOTSWITCH" jack on the rear panel. This allows remote control of the Reverb and Vibrato effects.
