Hi,
I recently purchased a fine old ES-125 that has what appears at first to be a sunken top (due to the extreme height needed at the bridge to keep the strings off of the frets). It also has seam separation in the back (and all of the braces have separated off the back and are rattling around inside).
The kerfed tonebar braces on the top don't have any cracks that might cause a sunken top; however, I suppose there is always the possibility that the heat environment that caused the back braces to become loose may have loosened the tone braces on the top enough to allow them to slip (?) before the glue re-hardened, and maybe allow the top to sink...not sure.
Can the back problems such as those I've described cause the action problems (maybe causing the neck to change angle as the back flexes), without there being any tonebar damage to the top?
I'll upload a few pics this eve.
Thanks for any ideas.
