Sorry about another pesky plywood question. It's just that you guys have been so helpful. My 1962 Kay was an old high school bass, which I saved from a trip to the Dumpster in 1982. It was in very bad shape, but my dad and I restored it. This included making a new sound post, as the old one was nowhere to be found. I wish I could remember how we did this with a radial arm saw. The belly has a noticeable depression under the G side of the bridge. There is a less pronounced bulge on the back. It was that way when I got the bass -- don't know if it has gotten worse in the past 20 years. Is this a symptom of all ply basses? Currently there is roughly one sound post's width between the sound post and the bridge foot. Will this continue getting worse until something really bad happens? How about carved basses?
