Good to know
- These are steel strings for acoustic (steel-string) guitars. Do not fit them on a classical (nylon-string) guitar.
- Change all strings together for an even tone, and retune a few times while new strings settle.
FAQ
Will GSA12 fit my guitar?
It fits 6-string steel-string acoustic guitars.
How often should I change strings?
When they sound dull, look discoloured or will not stay in tune. Players who practise daily usually change them more often.
