What shall I do.
If I change the strings on my 6 string tanglewood when I get home from work saturday morning and over tune them to stretch the strings and leave the guitar for 10 hours highly strung in a warm room do one think it will be ok for playing my 20 min slot at otford........

or
Shall I leave the old strings on. The old one are not .........to bad a condition.
