EDITOR'S NOTE: Patent Pending. After developing this concept extensively over the past year, I am very excited to announce a micro-partnership with Townsend Machine to bring the fully refined tuning system direct to market. Learn more at eLUTHERIE.org | Townsend Machine where I've posted in an in-depth article.
Back in February, when Monster and I evaluated Orchid, we agreed that a body-mounted tuning system would be beneficial, particularly in a 5-string model. It gives the luthier more design control over instrument balance, and moves the process of tuning to the plucking/picking hand, leaving the other free to fret.
a. less movement = more efficiency
b. efficiency = comfort
Over the years I've seen many variations on body-mounted tuners, the two most notable examples: Steinberger, and Kubicki. Both are simple machines: Steinberger based on a screw, Kubiki based on a pulley.
NOTE: Headstock-mounted tuners are (mostly) based on gears, a level of complexity beyond "simple" machine.
Both designs are elegant: Steinberger a compact monolith of efficiency, Kubiki a clever and intricate self-contained world of ingenuity. But I wanted something different. Something original to match the originality of Headless Monster. Something with potential to be better than previous designs.
Goals for my design:
1. Simple machine (manufacturing simplicity)
2. Virtually indestructible (Pete Townshend)
3. Works in any conditions (under water, sand storm, etc.)
4. Self-explanatory (use & adjustment)
5. Easy maintenance (graphite & go)
6. Lightweight (design simplicity)
7. Ergonomic
8. Zero-play mechanism (no sloppiness or slack)
So, I decided on a first-class lever.
I built a crude prototype (photos below) and experimented with the fulcrum position until I was able to comfortably tune a (bass) E string to pitch using just my fingers against the lever...in fact, the screw is simply a locking mechanism to hold the string at a given pitch. It's really fun to take a slack bass string and — bwriong — pull it to pitch.
The drawing represents my thoughts-of-the-moment. I'm developing prototype headstock termination points and saddle concepts. All parts of stainless steel, requiring several human lifetimes to wear out. Aircraft-grade aluminum would be a second choice.
EDITOR'S NOTE: Designed to interface with the patented (US 7,795,516) Neutral Tension Bridge.
