gearless tuner features
New technology fulfills the 30 year dream
of tone plus sustain. Remember the old beautiful
rich tone and everlasting sustain of
the long-scale steel guitars? Due to excessive string breakage, scale lengths
had to be shortened when pedals were added to steel guitars. Even though
this also reduced sus- tain and tone quality, it was necessary to keep the
strings on the guitar. Sierra's advanced
engineering and manufacturing quality of the 'Gearless Tuner' allows
a 25-inch scale with shorter string length than a keyed or
geared guitar with a 24 inch scale. This, united with Sierra's super-strong
body construction, makes the 30-year dream of tone plus sustain a
reality! Sierra's Gearless
Tuner gives the benefits of 'keyless' design that has been written
about for years. Yet the Sierra design is tuned 'on top' of the instru-
ment with finger-knob adjustment. The finger knob adjusting screws
raise or lower the string tension through a precision lever, giving
a micrometer fine adjustment. Machine head backlash is eliminated
and the historical string stretch problem behind the roller nut is
cured. Extensive
testing proved string hysteresis theories true. Sierra's gearless
tuner solved
this problem. Actual laboratory tests with a strobe tuner proved
that even the historically troublesome strings (4 & 8), with
both raise and lower functions, would return to true pitch with
zero
flat/sharp troubles. The design also allows for a shorter guitar
body. Gearless
models are all 31'/2 inches long. 5 inches shorter than a 'standard'
14 string guitar Of course, this means less weight!
- 1. Allows first fret playing and sliding off neck/roller
without obstruction.
- 2. Ideal leverage for micrometer-like ultra-fine
tuning.
- 3. Clean, modern appearance.
- 4. Easy string-to-tuner coordination.
- 5. Finger knob adjusting screws.
- 6. Improved string mounting. Easier, faster, and
tighter initial string installation.
- 7. No side movement of gearless fingers -- true
tracking.
