The Zoom G1X Four is a multi-effects processor designed for use with electric guitars, giving you an included expression pedal to provide continuously variable control over certain effects. Offered in an easy to use stompbox format, the G1X Four sports a wide selection of processes, amp emulations, and other features, such as an onboard 30-second looper and a chromatic tuner. With 68 built-in rhythm patterns, you can add drum loops to the mix, which can quite helpful during looping.

Distortion, chorus, reverb, and more are all on hand, as are 13 amp models that simulate classic combinations. Some effects benefit from the use of an expression pedal, so you can change the effect's amount in a smooth gradual way. You can tweak the pedal's operation in the digital realm through the G1X Four's display screen, or physically, employing a 5mm hex wrench to change the torque of the pedal itself.
