Gittler Instruments introduced the newly designed Gittler Guitar this year at the NAMM convention.
The Gittler is particularly interesting due to the hex pickups and a 13-pin output for connection to Roland guitar synth systems. The lack of a fretboard does make it look a bit challenging to play, but fear not. As the site explains:
You will only notice the lack of a fretboard in relation to the new freedom you have discovered by bending the strings downward as well as sideways, thus improving the tactile command of your pitch.
