Guitar Pitch Stability System and a 7-Way Circuit for 3-PickUp Guitars    

Allows for topside restringing of Fender Stratocaster guitars using only original and add-on parts; also a unique 7-way symmetric circuit for any 3-pickup electric guitar.

Overview

GUITAR PITCH STABILITY SYSTEM:
Improves guitar pitch stability and requires no modifications to a guitar or any of its parts. It is a low profile design which pertains in particular to Fender Stratocasters or any electric guitars with a similar bridge plate and tone block design. This invention does basically two things. First, the guitar strings are rerouted topside giving a much softer string bend past the string saddles (similar to Gibson guitars) which significantly reduces string drag (friction) at the saddles. After “dive-bombing” downward or going upward in pitch via the tremolo arm (as with a Stratocaster), the guitar returns to its original pitch when the tremolo arm is released. Second, readjustable saddle clamps are used which hold and lock all six string saddles together in position and to the bridge plate after string height and intonation adjustments have been made. This is the only patent of its kind which reuses original guitar parts and has only add-on parts, which makes it the most cost-effective.

7-WAY SYMMETRIC CIRCUIT:
Applicable to Fender Stratocasters and provides the 2 missing pickup combinations. Uses either the original 5-position pickup selector switch (or as an option a simpler 3-position switch). A simple SPST (single-pole single-throw) mode switch provides either "one at a time" or "two at a time" pickup selectability. This is a symmetric circuit, whereby the 2 intermediate positions of the 5-position pickup selector switch always give the "three at a time" pickup combination for either setting of the mode switch. No additional holes need to be drilled: the bottom-most tone control can be replaced with either a toggle switch or a combination potentiometer / push-pull switch. This circuit also works for any 3-pickup electric guitar. Note: the use of a simpler 3-position pickup selector switch provides 6 of the 7 possible pickup combinations.

Primary Application of the Technology

Electric guitar manufacturers, musicians, guitar technicians, manufacturers or sellers of guitar kits or guitar wiring kits.

The Problem Solved by the Technology

GUITAR PITCH STABILITY SYSTEM:
Fender Stratocasters traditionally are strung with the strings contacting the string saddles and then going down into the guitar body forming a nearly 90 degree angle. With this patent, the guitar strings are rerouted topside at the saddles giving a much softer string bend past the string saddles (similar to Gibson guitars) which significantly reduces string drag (friction) at the saddles. The result is a significant improvement in guitar pitch stability (tuning) after using the tremolo arm (i.e. the guitar returns to its original pitch).

7-WAY SYMMETRIC CIRCUIT:
This 7-way circuit provides all seven of the possible pickup combinations for any 3-pickup electric guitar. Fender Stratocasters from the factory only provide 5 of the 7 possible pickup combinations.

How the Technology Solves the Problem

GUITAR PITCH STABILITY SYSTEM:
This is the only patent of its kind which reuses original guitar parts and requires only add-on parts. Two saddle clamps are used along with a clamp-connecting screw for holding all the string saddles together as a unit. Two additional screws are used which effectively anchor each saddle clamp to the bridge plate and tone block. It is a low-profile design which allows for individual string height and intonation adjustments. Since there are variations in dimensional tolerance build-up across six string saddles, in addition to different hole to hole spacings across all the tone blocks and bridge plates to which this patent is applicable, solid captive metallic shims are used with the clamp-connecting screw. This effectively allows for one "universal" pair of saddle clamps to be fabricated.

7-WAY SYMMETRIC CIRCUIT:
This circuit requires only a simple SPST (single-pole single-throw) on/off mode switch. It is a hard-wired circuit using parallel coil switching and existing guitar controls. There are no electronics required, thereby improving reliability.

Competitive Advantage

GUITAR PITCH STABILITY SYSTEM:
This patent improves guitar pitch stability over factory-built Fender Stratocasters, since with this patent, the guitar is restrung topside. Because this is the only patent of its kind which reuses original guitar parts, and requires only add-on parts, it is therefore the most cost-effective. No modifications are required to the guitar (it can be easily put back to its original condition).

7-WAY SYMMETRIC CIRCUIT:
This 7-way circuit provides all seven of the possible pickup combinations for any 3-pickup electric guitar. Fender Stratocasters from the factory only provide 5 of the 7 possible pickup combinations. It works with any type of guitar pickups (either single-coil pickups, dual coil humbucker pickups, or any combinations thereof). It requires the addition of only a simple SPST on/off mode switch which makes it very cost effective. This circuit also has an option which allows for the use of a simpler 3-position pickup selector switch, whereby 6 of the 7 possible pickup combinations are provided (still out-performing the factory-built Stratocasters).
