I got my Ibanez GSR-180 yesterday. Yay!
But, it had fret buzz so I adjusted the action and THE TRUSS ROD :O and it stopped buzzing. Now, whenever I press down say, the 12th or any fret, it makes a weird, almost two tone noise, and one of the tones is out of tune?
Could this be to do with the truss rod, or is it the new strings I put on (RotoSound 40-100)?
