The G5 is loaded with 145 incredible-sounding DSP effects. These include 123 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, Distortion+ and M-117R, Aphex Punch Factory, Moog MF-101, Ibanez TS808, Marshall Guv'nor, Fuzz Face, Big Muff, Pro Co Rat, ADA Flanger, Z.Vex Seek-Wah, and Boss OD-1, DS-1, Metal Zone, 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. Delays and natural-sounding reverbs include rooms, halls, arenas, plates, springs, and tape delay simulators, as well as dual effects such as compressor/overdrive, chorus/delay and delay/reverb. There are also an additional 20 expressive effects specially designed for use with the Z-Pedal.
In addition, there are 22 amp and preamp models—vintage and modern, tube and solid-state—based on the best from manufacturers like Fender, Marshall, Matchless, ADA, Mega Boogie, Sound City, Hiwatt, Orange, Carr Mercury, Two Rock, Diezel, ENGL, Bogner, and Krank. Each comes with its own distinct virtual cabinet, and you can pair any amp model to any cabinet model to further alter the tonal quality. You can even match the output of a given amp/cabinet model to the actual setup you're playing through (options include Direct, Combo Front, Stack Front, Combo Power Amp, and Stack Power Amp).
