Topic: Setup question
I've got a new(er) acoustic guitar that I haven't had a setup for, largely because it seems to play just fine. However, I like to change strings about every 6 months or so, and I like to try different gauges. Not too different (.010, .011, .012), but on my previous guitar, the guy who did the setup said "It's set up for .011's now," as if putting a different gauge on it would destroy my guitar.
Is there that much of a difference in the lighter acoustic gauges that the guitar's truss rod needs to be adjusted every time you change? I have no experience in doing this on my own, and wouldn't trust myself anyway. Suggestions?
