Adjusting the truss rod on an Epiphone Sheraton? Adjusting the truss rod to get rid of fret buzz
Posted 18 June 2013 - 02:29 PM
So far I have loosened the truss rod by 1/2 a turn. Doing 1/8th turns at a time. The string is still touching the fret though (I have left time for neck to settle by the way). Should I keep loosening, the screw is getting pretty loose and I'm paranoid about breaking something despite my small adjustments at a time.
I have read on these semi-acoustics that the action is naturally low, so should I keep trying to raise my action or leave it, hence why I am asking what the perfect action is. Or alternatively should I raise the height of the bridge? It's just I've read online, truss rod adjustment should precede any adjustment to the bridge but having made 4 adjustments now with no visible increased action height I'm wondering whether keeping going is wise.
In fairness the buzzing is almost gone, I can still hear it when I press down on the first frets and play though...I have a feeling that the buzzing may be coming from the bridge saddles also. I don't want to deviate from the focus of this topic but if anyone knows about the bridge causing buzz and knows how to fix it please tell me.

somewhere on the Gibson/Epi website is a page for "setups" that may be a great deal of help.
as far as the bridge being a possible "buzzer" check it for a "retaining wire", if it has one, you may need to wiggle/move/remove it as these CAN cause buzzing.
also, have you checked with a straightedge for a possible high fret (or more than 1)? it may be as simple as tapping a loose fret back into place.
the string isn't vibrating against the top of a pickup is it? that's another possibility.
an exellent source of setup/repair info can be had on this forum in some of the pinned topics at the tops of pages.
another GREAT source is the "Trade Secrets" section at Stewmac.com (Stewart McDonald guitar parts).
Sheratons are wonderful guitars & have a good fanbase...let us know how this turns out.
You won't hurt its feelings boy, play it like you stole it!

Lay the guitar down on a table, strum it, and put your ear next to it to see if it's coming from the saddles.

It's good to be cautious but you could maybe try a whole turn now. Give the neck some time to adjust. Keep going until you dial in the amount of relief you need.
I've had truss rod nuts go very loose on me as I turned them to add more relief. I thought I'd reached the limit of adjustment but kept going anyway. The nut started to tighten up again but the relief did increase and eventually I got what I needed. Weird.

That said, the 12th fret should not touch the string as you describe. You either have a back bow to your neck, or frets are out of level. As stated above, loosening the truss rod will not cause damage, but if it is completely loose, loosening it more will not change anything. 1/2 a turn is not an extreme adjustment.
Fret leveling is pretty much required to get action Nirvana from a lower priced instrument, as opposed to a Gibson which comes with lazer leveled frets from the factory. DIY fret leveling takes a bit of intestinal fortitude but it can be done, and the results can be quite gratifying. Ruby, my Casino, would absolutely humiliate any $3000+ Gibson E-330.
