HOG2 is a harmonic octave generator/guitar synthesizer that generates multiple octave and harmony sounds simultaneously. It follows every note you play, whether it's a single note, an arpeggio, or a chord. It generates 10 harmony/octave notes for the original sound, and can be controlled with seven expression modes. You can also control the sound in real time using the included expression pedal, a standard MIDI controller, or the EXP. foot switch on the unit itself. There's also no need for special pickups or modifications to your guitar.
