The SmartLIGHT 31 Series (silver) was a nice enough telecater style electric built with and top of the line components. It’s real selling point, however, was the FretLight system. Guitars with the FretLight system have LEDs embedded at each fretting position for each string. When connected to the Fretlight PLUS box this allows the fingering for chords, scales to light up on the fingerboard. By connecting to a computer with the SmartPORT 2- PC connection you could also jam along with MIDI tracks and interactive lessons.
