Create a logo for a music instrument // Guitar

To whom it may concern: We are developping a guitar learning device which name is FRET X * FRET X is a device, that once put between the chords and the neck of the guitar it will show a light patterns on each fret (according to a given guitar tab), and also to sense if the player has put its fingers into the right place, giving inmediate feedback to the user against the given tablature. * The FRET X is also connected to a mobile applications, that sends the data to the physical device on the guitar to represent the lights and to get the finger position sensors. * Guitar players can have their favorite songs tabs loaded onto the FRET X mobile application * Guitar teachers can set their tabs into the FRET X mobile platform in order to student to use at home. The FRET X is mean to be a cool device, easy to set into and remove out of any guitar (Electric or Accoustic) for guitar students ranging from 10 years old till 35 years old (girls and boys) The logo does not have to show a guitar on it, so we avoid confusing customers with specific guitars (the device / name will be use for other fretted instruments like Bass). FRET X Logo has to be easy to read and to show simplicity (to give the users the understanding that its easy to remove from the guitar or bass) FRET X is related with anykind of music (not heavy metal logo for example). Please post if further questions are needed.
