The ZOOM G2 FOUR and G2X FOUR give 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 and G2X FOUR take 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.
