The Hub

Hey all. I've got the above-mentioned guitar on my bench. It had a neck reset and what appears to be a new bridge pad put in 14 years ago. It's a crack-free guitar except for a couple of little hairlines running from the back of the bridge to the upper tone bar. I thought that was a bit weird. Inside, everything looks okay until I turn off the inspection light, at which point I can see the rosy glow of daylight through the top - this is just ambient shop light, not a focused desk lamp! I don't have a Hacklinger gauge, but experience tells me this is super thin. I recall T.J. Thompson and Mark Stutman discussing a phenomenon they'd seen in 1970's Martins with rosewood plates that was similar to this. - Dick Boak surmised it was an inadvertent thinning caused by the big stroke sander Martin used for finish sanding - a kind of rebound effect. It could just be aggressive cleanup after a particularly violent bridge pad removal. I don't know. I'm tempted to put a 1mm overlay on the area with the grain running parallel to the top, just to make sure. Thoughts? Feelings?
