I have a Procraft guitar (made in China) that gets out of tune very quickly - especially after 2-3 minutes of strumming. Specifically, the 4th and 5th strings get out of tune more than the other strings.
I noticed the bridge of the guitar has come up a bit. I have glued it, and have kept the guitar detuned for 24 hours. Hopefully, this will solve the issue.
If this does not solve the issue, do I need to change the strings? The bridge? Something else?
