Types of tuners
Instruments- discuss specific features, luthiers, instrument problems & questions
Hello! Yes, there are several types of tuners out there, all of which serve to tighten a string to pitch. Some do it more effectively than others. The difference is in their price, style, materials used, and appearance.
You could use screw eyes as they used to put on Tennessee music boxes, or use so-called zither pins which have a fine thread that goes down into solid wood. These are more difficult to use than the others, and are not suited to constant re-tuning. Getting them to the exact spot you want is not easy! And zither pins require a separate key or wrench to adjust.
Violin pegs could be used, or Perfection pegs which are actually geared mechanical pegs made to look like wooden pegs. Both of these require fitting their tapers to reamed holes by a qualified luthier.
Planetary pegs, such as the ones made by Waverly, are large and expensive, but very smooth in operation.
Guitar machines range from the very cheap, open-geared type to smooth-working, sealed Grover or Gotoh types with beautiful finishes.
Friction pegs are made for banjos, but work well with dulcimers. They don't like the heavier-gauge strings, however, and have a hard time holding them up to pitch. The strength of grip is adjusted by means of a screw in the end of the knob.
You can usually replace one type of tuner with another, depending on how the holes in the pegbox are done. Holes that are too large can be plugged and redrilled, but it's a lot of work.
As far as my Number 1 choice goes, it depends on what dulcimer I'm working on. Historic reproductions get tuners that are appropriate to their style (usually handcarved wooden pegs). Modern dulcimers can be fitted with just about any of the types. If price (and space) were no object, I'd use the planetary tuners.
