Before Cannonballs had really hit the market I talked to the owner. It was in the late 90's. I was buying my first new pro tenor. I discussed with him about selling me one directly and he was almost going to do it. Glad he didn't as those weren't that good. He described to me how they did some work on the necks. When they showed up in the stores I always would look at the necks as I remembered that conversation. I would frequently see a little grinding marks inside.
