STRADPET Dual-use Titanium Fine Tuner for Loop-end & Ball-end Strings, for Violin & Viola

Problem is they don't fit on any standard wood tailpiece. You have to adjust your tailpiece to mount this fine tuner. Why would i do that? If i want to switch back to my favorite one later on i have a problem. Beside all my hill standard german made fine tuners for fraction of the price accept loop and ball e strings. I have buy few of those and thorow my money. Should be selled with warning.

Good quality .

These tuners are currently the best on the market because they are compatible with ball and loop strings, they are made of titanium and are therefore lightweight and very robust, and titanium gives the strings a brighter sound. They are easy to install on ebony or rosewood tailpieces and are very esthetic. With these "fine tunes", tuning is easy and precise, and last but not least, they allow you to respect the 1/6 rule of the vibrating string between tailpiece and bridge, which was impossible with ordinary "fine tunes".

Wonderful product and all around service.Quick safe postage. HIGHLY RECOMMENDED!!!

i have not installed it yet. i understand it might require opening the tailpiece slot/hole a little. standard size?
