Keyless Tuning System

Tuning knobs remain level
Twin shafts provide a perfectly balanced leverage ratio
Fine tuning is much more precise than with keys
Available lever movement has a more than adequate safety margin
No roller nut is required as there is no measurable movement at the nut
The problem of returning to pitch when lowering and raising the same string is virtually eliminated
No tools required for tuning, however, a phillips screwdriver is required to change strings
Knobs are shaped to accept an 11mm socket

Advantages of the Keyless Tuning System

When using keys for tuning, the excess string length needed to reach the keys from the nut absorbs vibration, taking energy from the main body of the string and decreasing sustain which is eliminated with keyless tuning
Pedal and knee lever travel is decreased since there is less string to stretch and the pedal and knee lever action feels more solid
The length of the instrument is shorter, therefore stronger, minimizing detuning while pressing pedals
Strings break less frequently since less movement of the bridge cam is required to acquire the same pitch
Undesirable overtones created by the excess string length are also eliminated with the keyless system. These overtones are detrimental to the pure tone of the instrument, as they will vary with string gauge, string length beyond the nut, and the location of the bar on the strings.
