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.
Five effects can be chained at any time and in any order. You can save these effects in one of the 50 user-preset patches. Switch among patches (or banks of patches) quickly with the tap of a toe, so you can change your live or studio sound with ease. You can also change global characteristics to retain a sense of unity among patches. A three-knob tone stack and the overall output level knob do not change as you cycle through your sounds.
The pedal sports over 70 different effects, and you can edit or add more effects from your computer too. Simply hook the pedal up to your Mac or Windows machine over a USB cable and add effects from Zoom's Guitar Lab software.
The G1X Four provides one 1/4" instrument input, one 3.5mm input for mobile devices and media players, and a combined amp/headphone output. The unit runs on four AA batteries, giving you up to 18 hours of run time. You can also power the unit with a dedicated ZOOM AD-16 AC adapter, or over USB.
