The G3 provides a whopping 116 different onboard DSP effects and amp/cabinet models.
These include compressors, noise gates, filters, equalizers, and wah effects, as well as boosters, overdrives, fuzzes, phasers, and flangers, plus chorus, pitch shift, tremolo, vibrato—even ring modulation. There are simulations of both classic and contemporary pedals such as the MXR Dynacomp and Distortion+, Moog MF-101, Ibanez TS808, Marshall Guv'nor, Fuzz Face, Big Muff, Pro Co Rat, ADA Flanger, and Boss OD-1, DS-1, Metal Face, and CE-1. Original effects include Zoom's Noise Reduction (ZNR) algorithm and ExtremeDS, which offers the most powerful gain of any distortion effect in the world. You'll also find 20 delays and natural-sounding reverbs here, including rooms, halls, arenas, plates, springs, and tape delay simulators, as well as dual effects such as chorus/delay, compressor/overdrive, and delay/reverb.
The 22 amp models provided by the G3 include emulations of both vintage and modern tube and solid-state amplifiers from manufacturers like Fender, Marshall, Matchless, Mega Boogie, Sound City, Hiwatt, Orange, Two Rock, Diezel, and ENGL, each with its own distinct cabinet modeling that can be used to further alter the tonal quality. What's more, you can pair any amp model to any cabinet model for unusual, and often striking effects. You can even match the output of a given amp/cabinet model to the actual setup you're playing through (options include Line, Combo Front, Stack Front, Combo Power Amp, and Stack Power Amp).
