Zoom G2FOUR Guitar Muilti Effects Processor

Dial in Great Tone and Sound in any Setting – The Zoom G2FOUR Guitar Multi Effects Processor

The ZOOM G2 FOUR gives guitarists more tone variations than ever before thanks to all-new amp modeling and innovative IR technology. You’ll dial in amazing sounds right out of the box. The G2 FOUR takes amp modeling to the next level. They combine faithfully reproduced models of classic amps (and a few new ones, too) and pair them with cabinet models that utilize our new Multi-layer IR technology. This gives guitarists both great tone and the feeling of that “big stage” sound in any environment.

Multi-Layer IR

These Impulse Responses were captured from iconic cabinets at 3 different volumes and are blended and activated based on the volume of your guitar.

Historic Guitar Sounds
