Re-String Acoustic Guitars
One of the worst things when playing is to hear your beloved guitar start to lose its resonance. A simple Re-String to revamp an Acoustic Guitars sound does the trick. Problem is, it is time consuming and I’m not a huge fan of the process.
I have no quick answer (with the exception of hiring a guitar tech to do it for you), but it is critical unless you want poor tone and your fingers to hurt.
