Wittner Uni "Glaesel Piccolo" Fine Tuner / String Adjuster for Violin.
the device does not fit a standard violin tailpiece, it may have been intended for some exotic asiatic or ancient middle eastern instrument, but certainly not a modern one...hard to believe but I fell for it.
I guess I didn’t realize how to buy or set it up but I couldn’t use it.
The hook is set up to work above the stop bar in order to preserve after length and still use a ball end string. However, this makes the pick-point of the end of the string higher and thus the angle of the after length shallower than the rest of the strings. When you tune the string and put it under tension, it puts down-force on the tailpiece on the e-string side and inversely lifts the g-string side up. This affected the tuning of the other strings a bit as I brought the e-string in tune. The crooked tailpiece didn't have a huge effect on tone. It did, however, look really weird. I think these would be more suitable if you were planning to use four of them for all your strings. Then at least it would be balanced.
These are solid, well made, and maintain string afterlength. Mounted on the Fiddlerman harp-style tailpiece they helped improve the response and sustain over the long-lever style fine tuners for all four strings using synthetic core strings (in this case Vision strings). Depending on the tailpiece, you may need to file a groove in the stop bar for the top-mounted lever to extend all the way out, but that is a simple fix. This gives 2 mm of travel for the fine tuner, which is adequate for synthetic core strings (my only concern in purchasing these, but not an issue). I highly recommend these fine tuners as they maintain the string afterlength and although they do add weight to the tailpiece, the center of balance is moved back compared to the long lever style, which seems to help with response and sustain.
This was a nice little addition to my violin. Easy to install. Fits perfectly on a harp style tailpiece.
