 Rock Band 3 (2010) featured three guitar controllers.One was modeled after the Fender Mustang, with six string sensors stretching from the bridge to the location of the neck pickup of a standard guitar, and 102 buttons in 6 columns of 17 frets, which together create MIDI note data.A second was built with Fender as a fully functional guitar, with a bridge pickup "listening" to the strings and sending MIDI information to the MIDI port.
