Rob O’Reilly calls his Expressiv Infinity guitar “the world's most advanced MIDI guitar system,” and he may just have a point there.

The guitar features polyphonic tracking to let you play up to six notes at once, as well as a fretboard scanner that detects notes the instant that a string touches a fret. This allows for one-handed synthesizer-like hammer-on techniques, although a pick mode is also on tap so you can play the guitar in standard fashion.

Inside, the guitar hosts a 16Mhz processor that offers minimal latency, allowing notes to be sent over MIDI in an imperceptible 100th of a second.

And while the Expressiv Infinity’s shape is eye-catching, the visual effect is even more dazzling thanks to the body’s Infinity Mirror design, which provides colorful interactive control indication.

The upper part of the body features controls for volume, pickup selection, octave shift, tuning adjustment, infinite sustain note holds, MIDI volume, a pitch bend/modulation joystick and the fretboard scanner’s play mode. A trackpad located below the neck pickup can be mapped to control MIDI parameters for real-time tweaking.

All together, these features allow you to do everything from trigger external sounds to change parameters with a string bend, play in numerous tunings and put on a light show for your audience courtesy of the Infinity Mirror’s interactive control indication.

The Expressiv Infinity features single-coil pickups, locking tuners, a Tune-o-matic-style bridge with through-body stringing, and a balance bar for even weight distribution. It even features a convenient pick holder.

Outputs include a standard 1/4" jack, a MIDI output and USB. The guitar requires a battery, of course, which gives you six hours of playing time with the Infinity Mirror body turned off and three with it on.

The Expressiv Infinity retails for €1,499—about $1,700—and can be preordered from Rob O’Reilly Guitars’ website.
