Line 6's programmable stomp boxes are chock-full of classic guitar effects, with the power and versatility of their digital modeling technology. They are like a full collection of rare, boutique pedals in each box. These pedals provide 16 effects, 16 presets, optional expression pedal input for control of all effect setting, complete programmability, stereo in & out and True Bypass switching. The MM4 Modulation Modeler provides 4 programmable presets and its effects include Panning, Tremolo, Phasers, U-Vibe, Rotary Drum & Horn, Flangers, Chorus effects, Pitch Vibrato and Ring modulation. It may be powered by either four "C" batteries or the optional PX1 power supply.
After they finished designing POD, Flextone, AX2, Spider, and Amp Farm, Line 6 wasn't content to sit, rest, and read all the raves from reviewers and users. Not at Line 6; they were spending all their time thinking about what they could build to make a guitar player's life even more fun than it normally is. One day, it came to them: Why not design the first great sounding pedals with models of all the most in demand, classic, hard to find effects, make it fully programmable, and put it into a heavy duty, pro-quality, true bypass stompbox? So they did.
