Guitar Retrieval Legal Action

Summary

If a co-worker refuses to return your guitar, a firm demand letter can be effective. Clearly state the value and your intent to pursue legal action if necessary. If the issue remains unresolved, consider consulting a local attorney to explore legal options for property recovery.

more firm please and make a threat of legal action maybe civil or something, just need enough for him to comply
You could try something like this:
"Hi [Co-worker's Name],
This is a final request for the return of my Cort GH * guitar, valued at over $*, which I voluntarily left in your care. If I do not receive your cooperation in retrieving it from your mom's house, I will have no choice but to take legal action, which may include a civil suit to recover my property. I hope we can resolve this matter promptly without further escalation.
Thank you."
This message is more firm and includes a mention of potential legal action to encourage compliance.
