About Your Gibson GForce Tuning System

The Gibson G-Force Tuning System is based on the Powertone® system which was developed the Tronical Company®. It’s purpose is to make tuning a guitar both easy and precise.

How Do Auto Tuning Systems Work?

Transperformance ® has offered an auto tuning system for decades. Adaption of the Transperformance system occurred because installation required extenzive work to route and install multiple components.

Introducing the G-Force System as a factory installed part of new guitars more or less forced consumers to at least try it. Besides ease of simple tuning, the G-Force electronics allow for easy non-standard tuning such as drop-tuning.

Wikipedia describes the workings of this systems as, “The Gibson system uses the standard Tune-o-matic style bridge typical on their guitars, but modifications were made to have individual piezo saddles that transmit each string’s pitch to the microprocessor.[7] The computer analyzes the signal, and then controls each of the Powerhead Locking Tuners. Each tuner is run by a small servo motor that works in sync with the bridge to bring the string up to pitch by altering the string’s tension until it is within a desired tolerance.[2] The entire system is powered by a nickel metal hydride rechargeable battery pack housed in the control cavity of the guitar.”.1

Tuning Your Guitar with G-Force

During an electric guitar setup Tuning your Gibson Les Paul for Standard Tuning is actually quite simple. It’s much easier to do sitting down. Always make certain your battery is fully charged. Here are the steps for tuning your G-Force guitar:

  • Press the ON button one time.
  • Holding your guitar in a normal playing position, strum all strings at once. You will notice the tuning keys turning as needed to tune the strings.
  • If all of the illumintaed string indicators are GREEN you are done. If any are RED, strum that string by itself.
  • When all string indicators are GREEN, the system will turn off automatically.

Refer to the Gibson Owner’s Manual for instructions on Alternate Tuning. The website SixStringAcoustic.com offers this information for Alternate Tunings, “However, there are also several alternate tunings that you can select – plus you can program in your own custom tunings too.

The tunings that are pre-set are separated into Green and Red pre-sets. The blue pre-set is where you enter in your custom tunings. It starts out as standard tuning until you program in your custom tunings.

There are also low tuning pre-sets. These are the white and the yellow pre-set banks. Then there is a Magenta pre-set banks where you can do custom low tunings. The Magenta defaults to C tuning (which is C, F, A#, D#, G, C)”2.

One forum user stated, “I have had the guitar for one week, played it for at least 20+ hours and the G-Force tuners have presented me with nothing but problems. The last straw was at rehearsal last night and the guitar was out of tune more than it was in tune. I have purchased many, many brand new guitars over the years and never had the problems with tuning as I have had with this one.”4.
