I am about to change strings on my Seagull S6 slim which I bought last March and still has the original strings on it - I don't change strings often.
I am putting on D Dario 11 gauge flat wounds. Only because I have these on 2 other guitars and like the feel of them. In fact I would say for me, they rank a 10 only because I like playing flat wounds more than any other.
I'll give you a sound sample before and after if you want it Herman.
This year the diet is definitely gonna stick!
