Got my new guitar, a yamaha sa2200. Just beautifull. Maybe the most gorgeous top I´ve seen. I´ll post some pics later. It came with 0,9s. Ridiculus low action, but works great. Frets are a little low though, but incredibly smooth. I´ll be changing to elixirs 10-46 and be raising the action a little. Do I need to tighten the truss rod after that, and how do I know how much? The tail piece is basicly all the way down. I suppose that works with 0,9s, but I´m pretty sure it will be way to stiff with 10-46 elixirs. Do I just raise it untill I like the feel, or is there some rule? On this guitar the bass and treble side of the tail piece are at the same height, but on gibsons the bass side is usaly higher then the treble side. Is there a reason for this?
