I was asked to renovate and restring a classical guitar with the make "Donovan Excellence" for a lady's daughter to use. The guitar had not been played for thirty years and had old steel strings still attached. I told her it should have nylon strings, and she may have problems keeping it in tune or stress the neck. Can anyone identify the instrument and give me some advice on strings and value? It sounded great once I tuned it up and is it worth having a luthier work on it?

Yours, Aye. Dave
