Thx for the replies and welcome guys.
@Doug - I think I'll try some heavier weight strings before I mess with the truss. I've never had much luck in the past with trussrods. Oddly enough, the first truss adjustments I made to my very first guitar (an $79 Rouge dreadnought) worked like a charm and I played that thing until the frets wore down. I did it right with that instrument, adjusted 1/4 turn every week until the buzz went away. But you are right, my problems are most certainly b/c of climatic induced bowing. I just ordered a mess of different gauges, some with different gauge for top/bottom. I'm going to see if any of them get rid of the buzz, I'll post the results.
I did just learn something new and nifty about PRS trussrods, tho
The PRS double acting truss rod provides neck adjustment in both directions. Conventional truss rods can only compensate for forward neck bow. Due to varied climate and other conditions to which your PRS guitar may be exposed during its lifetime, we have made our necks fully adjustable.
Nice to know in case I need to try an adjustment.
I still think PRS is a quality guitar, tho, cause my strat-clone electric, which i thought was indestructable, dried out so much it popped up my pickguard this summer, revealing the innards (in which the assembly workers had dropped and left about 5 extra springs!! hah!). I miss that guitar tho - my first electric ...
