    Ratio tuners & String Saver saddles.

    I like these tuners very much. I installed them on two kanilea tenors and they tune up nicely and sound sweeter. I've also recently had ratios installed on a D28 and D18. Much improved, and since the tuning is more precise, the chords and overtones sound beautiful. I've had string savers on all our electrics since I first discovered you guys over thirty years ago. String breakage has been eliminated. That was once a problem, but hasn't been ever since. Thanks folks.

    So much easier...

    Well, they look great for one thing. They're much smoother to operate than traditional open gear tuners you get on the typical uke. Action is quick and sure. I think they're fantastic. Oh...and you can really feel the difference in the weight. I thought it wasn't going to be noticed, but as soon as I picked up my uke i could tell right away it was lighter.
