Had a small issue with one of the Sperzel tuners this week. As best I can tell normal tension from the strings pushed the fluted plastic sleeve that covers the winding post over and jammed it into the wood with enough force that it got stuck and I couldn't push it back myself no matter what I tried. Called Ken and he told me to send it back to him and he would fix it and send it back (at his cost both ways). To be frank he didn't seem to want to believe me that I couldn't just stick something small and pointy in the winding hole and nudge the sleeve over no matter how many times I explained to him that it wouldn't move even when I tried doing that and so he kind of treated me as if I was making a big deal out of nothing which was annoying. Then again, I tend to be the same way when trying to explain something which I think is very simple to someone who doesn't seem to get it, so it is really hard for me to fault him too much for that.
I dropped it off at my local luthier rather than burn the money and uke-less time to ship it back to Maui and back. They were able to dissasemble the peg, unstick the sleeve, and put it together. Ken told me to send him the bill but it was a small enough charge that I'm not going to worry about it. He actually put a new tuner in the mail to me yesterday before it was known that the local guy could fix it cheaply.
Again, I believe this is an isolated issue with the one Sperzel tuner unit, not with Ken. I do appreciate that Ken was willing to stand behind his work and make sure it was repaired properly. I'm back to happily strumming now.
