The ZOOM G2.1u is a multi-effects processor for guitar made by Zoom, featuring amp modeling and digital effects1. It combines a range of effects in a single floor unit, so a player can cover amp tones and time-based effects without a board of individual pedals. It belongs to the same family of compact guitar multi-effects as the Zoom G2 and the Zoom G2Nu.
What it does
The G2.1u pairs amp modeling with digital effects in one unit1. Its built-in expression pedal gives real-time control of volume, wah, and effect parameters, which means a player can sweep a wah or ride volume without a separate expression pedal1. Presets are stored and recalled using the onboard footswitches, so changing sounds during a performance is done from the floor1.
Power
The G2.1u runs on 9V DC, center negative, and draws 300mA1. That current draw is higher than many single pedals need, so a daisy chain supply shared with other pedals may not be adequate; a dedicated supply output rated for the draw is the safer arrangement.
The G2.1u is a digital unit, and its 300mA current draw at 9V DC should be checked against what your power supply can deliver1.
Where it sits in Zoom's range
Zoom's multi-effects line includes compact floor units like the G2.1u, which combines a digital effects processor with a built-in expression pedal for real-time control of volume, wah, and effect parameters1. Presets are stored and recalled using the onboard footswitches, so the unit is designed to be played rather than adjusted by hand mid-song1. For a broader view of the category, see Multi-effects Pedals.
