So I have my guitar set up just how I like it - Low action, and the neck as straight as it'll go. And it plays great. But the issue is some buzzing on the upper frets and open strings (when you really hit 'em hard). I tried tweaking the truss rod to fix it, and got nothin'. I've run into this issue before, and I know it is the low-tension of the 9's I use. I know that I could solve the buzzing by just putting a set of 10's on, but I really love my 9's. Sooooo, what could I do? Should I try and 9 1/2 set? Is there a certain brand that may have more tension to 'em (I know this is unlikely, but I heard some guy say that GHS Boomers "have more tension")? Would top wrapping maybe increase the tension? I am currently using EB Super Slinkys on a Les Paul scale guitar.
