A snapped tremolo on an electric guitar is a broken connection between the trem block and the tailpiece, which causes the guitar to go out of tune when the tremolo arm is used. This can be a frustrating and expensive problem, but it is one that can often be fixed at home with a few simple tools.
Here are the steps involved in fixing a snapped tremolo:
1. Remove the strings from the guitar.
This will make it easier to work on the tremolo and prevent the guitar from going out of tune.
2. Unscrew the back cover of the tremolo cavity.
This will expose the tremolo springs and the trem block.
3. Remove the tremolo springs.
This can be done by simply lifting them out with a pair of needle-nose pliers or by using a spring removal tool.
4. Remove the trem block.
This can be done by turning it counterclockwise and lifting it out of the cavity.
5. Inspect the trem block and the tailpiece for damage.
If there is any damage, it will need to be repaired before the tremolo can be reattached. If there are any broken screws, you will need to replace them. If you find any cracks or major damage, you may need to replace the entire tremolo unit.
6. Reattach the tremolo block.
This can be done by simply placing it in the cavity and turning it clockwise until it is snug.
7. Reattach the tremolo springs.
This can be done by simply inserting them into the holes in the trem block and pulling them up until they are taut.
8. Replace the back cover of the tremolo cavity.
This will help to keep the tremolo mechanism in place and prevent it from coming loose.
9. Reinstall the strings on the guitar.
Tune the guitar and check that the tremolo is working properly.
If you are not comfortable performing any of these steps, it is best to take your guitar to a qualified repairman.
