Hello! I have a G&L Tribute L 2000 that I've been struggling to get a good setup on. I now have it setup so that I get minimal buzz when digging in but it's way higher than I'm used to. Action is way over 3 mm at 17th fret and the relief is about 0.3 mm. The factory specs call for around 0.12"-0.14" relief at 8th fret and a action of 3/32" at 17th. I'm way over that... If I lower the action more to spec I get an ok amount of buzz att the lower frets but way to much buzz from 9/10th fret and higher. It's across all the strings but low E string (dropped to D) is worst and choking when not played REALLY light. I've noticed that there's a small shim att the neck joint (bridge side) made from a thin strip of sandpaper (Probably from factory). My understanding is that you only shim a neck like that if the bridge saddles are bottoming out and you can't get the action any lower. My problem is quite the reversed, so why is there a shim there? Is there a chance that this shim might be the reason for my high action and the fret buzz att the higher frets? I play in drop D with a 45-105 Guage of Elixir nickel string and I do play rather hard with a pick. A decent amount of buzz is allright acoustically but not like this. Any other tips that might help me to get a lower action? Increasing relief?
