About a year and a half ago I bought a Ernie Ball John Petrucci 7 string model. I had the store set the action low because I find that more comfortable. It has been great ever since until recently. I picked up my guitar 2 days ago and all of the strings were buzzing at the lower frets to the point where they would not sound a note. Everything seemed good up above the 12th fret. I made a small adjustment to the tension spring claw for the bridge the last time I changed the strings. I do not know what is causing this problem. I recently moved to a more humid environment, I don't know if this could have anything to do with it. Somebody please help!!!
What type of bridge is it?
It's the one that came stock on the guitar. It's a floating non-locking with pretty standard string saddles.
i dunno it might be the strings, it might be the tension. is the action noticeably different?
I used the same strings. Ernie ball 7 string set 10-56. The action was low to start, with a light buzz. But this was just dead notes pretty much every fret above the 12th.
Above as in 13 or as in 11? It might be the truss rod.
It could be the strings getting old, or, more likely, the neck has moved because of the humidity. You can either adjust it yourself (you should know what you're doing) or take it in to get it set up again.
Would the difference in humidity from California to Oklahoma really make that much of a change in the truss rod? It's a 5 bolt, bolt-on neck. The only way to adjust the truss is take off the neck. How much should it be adjusted?
Above as in 13 and higher. It was the same way with new strings.
changing from Cali to OK could do it, different temps and humidity. should be a simple fix. please see the setup thread in EG.
