Offer Details

Get a complete collection of guitar effects, amp-inspired tones, recording features, and practice tools in one compact floor unit with this Zoom G2.1u Guitar Multi-Effects Processor.

The G2.1u offers 54 effect types, with up to nine effect modules operating simultaneously. Its effects include compression, wah, Zoom Noise Reduction, overdrive and distortion, amp and cabinet simulation, EQ, chorus, flanger, phaser, pitch shifting, delay, reverb, and more. A built-in expression pedal provides real-time control of volume, wah, modulation, delay, and other assignable parameters.

Unlike many basic multi-effects pedals from its era, the G2.1u also includes a USB audio interface, allowing processed guitar signals to be sent directly to a compatible computer for recording. It is equally useful as a compact stage processor, home-practice setup, headphone rig, or desktop recording interface.

This example shows normal cosmetic wear from previous use, including light marks, dust, and surface wear visible in the photographs. The battery cover is present, and the input, output, control, USB, and power connections all appear intact. Please examine the photographs carefully, as they show the actual pedal being offered.

Serial number: 051266
Country of manufacture: China
Approximate production period: Mid-to-late 2000s

The G2.1u was introduced around 2005–2006. Zoom does not publish a dependable serial-number dating chart for this model, so the exact manufacture year of this individual pedal cannot be confirmed from serial number 051266. I would list it as “circa 2006–2009” rather than claiming one exact year.
