Hello! Newer user and first-time poster here. I've searched through the forum and read lots already about guitar setup but still need help. Here are the quick details: Trying to lower the action on my Strat and am still getting buzzing around the 12th fret on the middle strings. Strings are D'Addario .011-.046 (not sure on low end gauge). Radius is 9.5", Relief is ~.05, trem (3 springs) is floating at about 1/8", action is .095-.125 high E to low E. No buzzing on frets below 12 fret, and worst offenders are D and G strings. I would really like to lower the action more if possible, although I do like to bend. Read David Collins post about straighter neck being better for less upper-neck buzziness. Thoughts? Should I shim the neck? I need to get it in to check nut height and fretwork, but would like any at-home solutions first. Thanks!
