The Zoom G1X FOUR is a digital guitar multi-effects processor from Zoom, the version of the G1 FOUR that adds Zoom's built-in expression pedal. It carries over 70 effects and amp models, a looper and a drum machine, and was released in February 2019 at a list price of $99.99 in the US12.
The expression pedal is the headline difference: it provides control over effects such as volume, wah, delay and pitch, giving you real-time foot control without adding a separate pedal to the board3.
Controls, modes and the expression pedal
The G1X FOUR has two footswitches, with up to five effects usable per patch4. Zoom describes two performance modes for switching sounds during live shows: PRESELECT mode and STOMP mode3.
- PRESELECT mode: one of the two performance modes for changing sounds during live shows3
- STOMP mode: the second performance mode, letting you treat effects like individual pedals3
- Expression pedal: controls effects such as volume, wah, delay and pitch3
The expression pedal follows a line Zoom has used before. The earlier G1Xon had a built-in expression pedal that let you control input level, output level, or any selected effect parameter7, and that unit also carried an onboard chromatic tuner and looper8.
Looper, drum machine and effects
Zoom describes both the G1 FOUR and G1X FOUR as featuring over 70 effects and amp models, a looper and a drum machine3. That combination makes the unit a practice tool as well as a live one: the looper and drum machine sit alongside the effects in a single floor unit.
G1 FOUR versus G1X FOUR
The two models share the same effects library, looper, drum machine and power options. The difference is the expression pedal: the G1X FOUR comes with it, the G1 FOUR does not. At launch the pair retailed at $79.99 and $99.99 respectively, a $20 difference between the two list prices12.
