With Firmware V3.0, which is free to download, you’ll have even more ways to craft the perfect guitar tone. Firmware V3.0 gives you access to the all-new MS-50G Effect Manager, allowing you to view and manage effects on your pedal, as well as download 72 brand new effects.

Here’s a snapshot of the effects available for MS-50G:

Dynamics / Filter
Shape and control your sound with these 25 compressors, equalizers, and filters, plus Zoom's Noise Reduction (ZNR) algorithm, designed to remove noise during pauses while still maintaining your instrument's natural tone. Other options here include automatic Slow Attack, AutoWah, and Cry, as well as emulations of the MXR Dyna Comp, Moog MF-101, and Z. Vex Seek-Wah.

Overdrive / Distortion
The MS-50G's 32 boosters, overdrives, and fuzz tones include simulations of the BOSS OD-1, DS-1, and Metal Zone, as well as the Ibanez TS808, MXR Distortion+, Matchless Hot Box, Electro-Harmonix Big Muff, and Pro Co Rat. Our ExtremeDS effect offers the most powerful gain of any distortion effect in the world, and there's even a simulator that allows your electric guitar to sound like an acoustic.

Amp
The 22 amp models provided here include emulations of classic and contemporary tube and solid-state amplifiers from manufacturers like Fender, Marshall, Mesa Boogie, 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. The MS-50G also provides you with the ability to 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).

Modulation / Special effects
You'll find 39 different modulation and special effects here, all specially crafted for guitar. These include phasing, flanging, chorusing, tremolo, vibrato, detuning, octave dividing, and pitch shifting—even an intelligent harmonizer that plays along in key. Vintage sounds include simulations of the Boss CH-1 Super Chorus and ADA flanger.  

Delay / Reverb
The MS-50G's cutting-edge DSP microchip performs 32-bit floating-point calculations, giving it the ability to create sophisticated studio-quality effects such as the 29 rich, dense reverbs and realistic spatial simulations found here. These allow you to place your guitar in natural-sounding spaces such as rooms and halls or to add delays of up to 4 seconds. There are 25 types of delays available for MS-50G. Also included are reverb plates and springs and a tape delay simulator, as well as reverse, modulated, and self-oscillating delays.
