Wittner Cello Tuning Pegs 4/4 12,5

This is a product for tuning your acoustic instrument from Pegs.

I know this product from my colleagues. I immediately order once I realized that they made for Cello also because I have several problems to tune my cello with the fine tuner in the tailpiece. I can't use them while using my bow.
I order the product and spent around 50 Euro for installation to my local luthier.

Now I can tune my cello same time using my bow hand. It is saving my time and have a better result. Also, I don't need to tune often as pigs are holding tune very well.
I recommend this product for every level of players.

Only negative part maybe for fancy instrument players may be because the design is standard and one color. But this is not the case for me.
