  If the sound from your Roland Guitar amplifier is distorted or noisy, there are a few potential causes. First, check if each [VOLUME] knob is raised excessively; if so, turn them to the left to adjust the volume appropriately. Also, the input level from the connected device might be too high, so try lowering its volume. Finally, exhausted batteries can cause distortion or cut-offs at high volumes. Replace the batteries or use the AC adapter (sold separately).

  If you're experiencing no sound or insufficient volume from your Roland Guitar amplifier, first ensure that all connections with other devices are correct. Check them again to be sure. Next, verify that the [VOLUME] knob is set appropriately and adjust it as needed. If headphones are connected, the unit's speakers will be muted. Also, note that the MOBILE AC does not support condenser microphones requiring phantom power.

  Lori WernerAug 22, 2025
  If the volume level of a device connected to the AUDIO jacks on your Roland Guitar amplifier is too low, the issue might be the connection cable. Ensure that you are not using a connection cable that contains a resistor, as this can reduce the volume. Use a cable without a resistor instead.
