For those who have trouble tuning violin and cello strings with
pegs, these FineTune Planetary Pegs by Wittner provide
easy, quick, effortless and very fine precise tuning without any
need for finger pressure towards or away from the peg box. Eliminate
those tired and/or sore fingers.
Made from high-tech composite material and light alloys, these
tapered pegs are put in place without any glue. Simply press the
peg into the pegbox like any ordinary peg. The self-inhibiting
transmission (8.5 : 1 gear ratio), inhibits string from
losing any tension. The FineTune Peg (the shaft) needs not to
be loosened or tightened in order to tune the instrument. Subsequently
there is no friction, no wear on the peg or the peghole (no maintenance).
Simply turn the head of the peg without any effort at all until
intonation is correct.
