They're just putting them in too bloody tight. We used to have the same problems with new Kimballs for the same reason. Every year for the last five years or so, the Yamaha pinning seems to get tighter. Why are they doing this? The Thomaston products are now very difficult to tune, and I battled a new U3 last week that was virtually untunable for this reason. Ron N
