Supplement Troubleshooting

[Mini Electric Guitar with Built-in Amp and Speaker]

The coil wire has broken.

  • Join the two broken ends and continue winding. The coil wire has a transparent coating and this should be removed using sandpaper or the like. Following this, ensure that the strands are well wrapped around each other.

The guitar does not produce any sound when turned on.

  • Confirm that the batteries are new and that they have been inserted in the correct direction.
  • Ensure that the pickup and battery connectors have been securely fastened in place.

Increasing the volume has little effect.

  • Ensure that the speaker is facing the correct direction. (The front of the speaker features the transparent cone, and this should be facing outward.)
  • Indentation of the transparent speaker cone can also cause the volume to stay low. In such a case, cellophane tape can be used to pull gently and fix any indentation.

Turning the tuning peg does not cause the pitch to rise.

  • The initial string tension may be insufficient. Remove the neck cover, loosen the washer head screws used to secure the string in question, increase the tension in the string, and then retighten the bolt.
  • Note that excessive tightening of the tuning peg can damage the threads on the tuning shaft. If this has occurred, remove the string in question, move the peg lug to a position beyond the damaged threads, and then tighten the string.

The guitar cannot be tuned properly.

  • Check whether the bridge has become detached or is angled incorrectly.
