Hello everyone! Here is another Sovereign post for ya. My cousin, for whom I pay bass, had a string break and he was unable to get the guitar to stay in tune after that and switched guitars in the middle of practice. Seeing as how I'm cutting my teeth in the guitar repair biz, he asked me to see what I can do.
The condition: The guitar has no loose bracings or cracks, the bridge is completely sound and firmly planted (it's the kind that is strung from the top of the bridge, not through the guitar top with pins), the saddle is every so slightly slanted, but is almost straight like a classical. There was a cheep "repair" job done years ago in lieu of a proper neck reset. The dove tail was sawed through along the body to just shy of the fingerboard, bent back to correct the angle and re-glued and further anchored by a wood screw through the heel and block. The heel joint looks solid, no cracks or splits though there seems to be only hardened glue between the heel and body toward the the fingerboard.
My assessment: I was able to get the guitar in tune with no problem in my shop, though the G string is severely out of tune when fretted and played with any other string open or fretted. The intonation is correct or very very close for all strings but the G, which is about a 1/4 tone off. This makes sens with an almost straight saddle on a steel string guitar. I can play anything all the way up the neck, and as long as i play the G open, every thing is in tune.
He claims that in all the years he's owned it, it has never had an intonation problem until Monday when he broke the string.
I don't know what to think. All looks solid to me, and the truss rod seems to do it's job, though I wonder how the repairman managed to cut through without cutting through the truss rod too. There is a slight rattle when tapping hard on the center and rear of the neck, but nothing too alarming in sound.
Can anyone tell me if there is something in the neck perhaps, or elsewhere, that could have shifted causing this intonation to go out on the G when the string broke?
All I can see to do is widen the saddle slot, and set another one and do a zig-zag shape in compensating it.
Thanks for your thoughts!
