This is a local musician's main acoustic. It's a 2014 Gibson J-29. As you can see the bridge was lifted when I got it, and the top has been pulled up into a bulge. The bridge came off pretty clean, but I noticed how the spruce broke behind the pins. I didn't score this side of the bridge, but it looks like it must have been scored for the wood to break that cleanly. Could this have come from the factory like that? I don't know why Gibso…

Hello everybody, I am about to embark on building an acoustic with a top other than spruce. I have some mahogany and looking to buy some koa. I have always heard and read that when looking for spruce tops that the tighter and straighter the grain on the top the better. Should this hold true for other species as well. For example, looking at the sample koa selection in the picture would the center option have a better sound than the optio…

Torrefied Spruce Tops , current client is asking about it for his build. I have not had any experience here. Thoughts, comments, Thanks

Long story short, Mom's sitting next to her guitar and POW, the bridge pops off taking part of the top with it. Now I'm trying to figure out how to fix it and I would like your feedback on my plan below. The hole is roughly the same size as the bridge. The top is a 3-layer laminate. The bridge, top, and bridge plate all came out as a single unit. The glue on the braces behind the bridge has failed, so the top will need to be re-glued…

@member @member I have a question for you. I'm starting to measure spruce for a couple of classical guitars I'm going to make. I used structured sides (I'm calling them cored) on one of my last guitars and it came out notably great. I accidentally thinned the top more than I might have and it seemed to work very well. My thought is that the sides are so stiff that it's allowing the top to survive structurally even…

This is a Suzuki violin company 'Three S' OM-style guitar, circa 1970s. This particular instrument was sold in the Japanese domestic market (my customer purchased it in Japan) but I've seen others in circulation here in Australia so presumably some were exported too. Sides and back are laminated rosewood, the top is solid spruce. Although this ended up being a relatively standard reset, I feel like this is worth documenting as prior to…
