How Our Competitor’s Systems Work

Our competitors use inferior analog feedback approaches to solving the tuning problem. These feedback approaches have many problems, limitations, and disadvantages.
During the analog feedback process, the strings must be vibrating while their fundamental frequencies are determined and compared to a set of reference frequencies. In order for this to work, the strings cannot be fretted or bent. As a result, you cannot change the tuning of the guitar or play the guitar during “their”analog feedback processes.
Additional problems are created during the feedback process because the string frequencies are decaying while they are being compared to constant reference frequencies. As a result, the motors overshoot the string frequencies and dance around the target note until the strings die out. With luck, the strings stop moving while they are passing over their requested notes. If any string stops ringing before the tuning process is complete, all the strings must be re-strummed until they are in-tune. This makes it virtually impossible to tune the guitar with any level of speed or accuracy.
Some of our competitors put the adjusting mechanisms behind the headstock of the guitar. This creates additional problems because the strings need to travel through the nut of the guitar. It is well known and documented that friction exists in the nut making it virtually impossible for these systems to have any reasonable level of accuracy or reproducibility.
