The Line 6 MM-4 Modulation Modeler is a fully programmable multi-effect pedal that brings together 16 of the most iconic and sought-after modulation effects in one rugged, pro-grade stompbox. From the lush swirl of the CE-1 Chorus to the deep swoosh of the MXR Flanger, and even rarities like the Tri-Stereo Chorus and Mutron Bi-Phase, the MM-4 recreates them all — along with original Line 6 designs — with rich, dynamic digital precision.
Four fully programmable presets can be accessed instantly by footswitch, eliminating the need for multiple modulation pedals on your board. The control layout is refreshingly simple: just six knobs — Effect Selector, Speed, Depth, Tweak, Tweez, and Mix — giving you hands-on access to every parameter with no menus or complex programming.
The MM-4 features true bypass switching to preserve your direct tone, stereo inputs and outputs for expansive signal routing, and an expression pedal input for real-time control over multiple parameters — even allowing you to morph between settings for entirely new, evolving effects. Whether you’re dialing in a subtle tremolo or full-blown rotary speaker madness, the MM-4 delivers it all in a compact, road-ready format.
This unit has been fully tested and is in excellent working condition. It comes with the correct 9V AC adapter.
