So I want to permanently tune a whole step down on my Carvin guitar. It has a fixed bridge, two graphite reinforcing bars in the neck, and it was recently professionally set up for 10's. I want to put on strings, that with the new setup, will give the feel of 11's (12's tuned down a whole step??). My plan was to take it to the shop to get set-up again...but if I can get away with doing it myself, I dont want to waste my money. I mean, I can make a simple truss rod adjustment,but I'm not familiar with setting up intonation (not having a decent tuner doesnt help that), feeler gauges, and setting the action and that sort of stuff. So what do you tech-gurus think?
