1950 Martin D28 with localized scary thinning.

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…

In classical woodworking theory, yes - crossgrain glue-ups are a real no-no, but we get away with it in guitarmaking all the time. We're the rebellious bad boys of woodcraft! In this case I went w…

Trying to pass on the love

Hey everyone. This is a first time post for me, but I wanted to say thank you for everything. I’ve been tinkering here and there for the past few years under the eye of a former Martin employee, but this group has really given me more courage. In a high school math teacher by day. I teach mostly Geometry and Algebra. One of my students stayed after for help the other day and had his guitar for guitar class. I asked if I could see it and i…

That’s a great story. You are the man! That kid must have been blown away. And now there’s one more person out there that guitars can actually be worked on and set up. As opposed to, it came from the…
