Description

The Zoom G1 Four is a compact and powerful multi-effects processor designed for guitarists who want a wide range of sounds at their fingertips. With over 60 built-in effects, including distortion, modulation, delay, reverb, and more creative options like sitar simulation and pitch-shifting delay, the G1 Four makes it easy to shape your tone in unique and expressive ways. It also includes 13 classic amp and cabinet models, so you can take big-stage tones anywhere.

Perfect for practice and performance, the G1 Four features a 30-second looper, 68 built-in drum patterns, and Zoom’s Guitar Lab software, which gives you access to an ever-expanding library of downloadable effects and patches. You can chain up to five effects simultaneously, use Auto Save to instantly back up your changes, and switch seamlessly between patches with Preselect and Stomp modes. Whether you're jamming along to rhythms or building multi-layered arrangements, the G1 Four keeps you connected to your creativity.

Designed with portability in mind, the G1 Four runs on four AA batteries, USB bus power, or the optional Zoom AD-16 adapter, and its intuitive interface works equally well on the floor or a desktop. Additional features like an onboard chromatic tuner, aux input, and combined output/headphone jack make it ideal for home practice, rehearsals, or travel. For guitarists of any level, the Zoom G1 Four is a versatile, affordable way to explore new tones and stay inspired wherever you play.
