I just pulled the D string tuner, and it was notchy off the guitar. It also had lots of lash. I tightened the screw on the shaft, and that eliminated the lash. All, of the shaft screws were barely finger tight, so tightening them down a bit got rid of the lash. They're still not as smooth as standard Gotoh tuners on my classicals, and not even in the same galaxy as Gotoh 510's.
The Taylor tuner buttons are too small, IMO. Are the Waverly buttons any larger, or do the Waverlys work well enough that larger buttons aren't necessary? I'll be ordering the Waverlys from StewMac, and they don't provide button dimensions.
Thanks!
Edit: The Taylor plates left an impression on the side of the headstock, but I'm guessing the Waverlys will cover that. The Taylors have a 1/4" roller, so the Waverlys shouldn't be a problem. Besides, I've done 10mm to 3/8" plenty of times with classical guitars. I don't use power tools for that, but have seen the unhappy results from people who do.
