uTune

About

A practical issue faced by guitarists is the constant need to tune and re-tune the guitar. Firstly, guitar strings constantly go out of tune with increased play time, changes in temperature, and time spent unused. On top of this, many songs use tunings different than the standard EADGBE, such as DADGBE (known as “drop D”), DADGAD for fingerstyle songs, full downward shifts like D#G#C#F#A#D# or DGCFAD, and song-unique tunings like CGCGGC or CFCFAC.

The six tuning pegs located on the headstock of a guitar must be turned manually by the guitarist to adjust the pitch of each string, one by one. This tuning process takes significant time and effort in a guitarist’s performance, day, and week due to how often the above situations call for new tuning.

uTune automates the tuning process through the use of frequency analysis, a feedback-loop control system, and high-torque motors. uTune successfully solves the problems of the time and effort to tune faced by guitarists.
