The HOG 2 (Harmonic Octave Generator) is an effect that adds harmonics that weren't present in your guitar signal for a versatile range of effects that defy the imagination. Organ and synthesizer sounds are the name of the game here, and with the HOG at your feet it's easy to cover keyboard parts or create completely new sounds never before heard before. Seven unique expression controls offer a wide array of combinations of the on board effects, such as freeze and gliss, octave or step bends, and wah and filter effects. A pair of envelope generators allow fine tuning of the effect and lets you create effects that swell with exceptional movement. This HOG 2 comes to us in excellent, like new used condition, free of any scratches or blemishes. The original box, power supply, and expression pedal are included in the sale.
