The M1 is latest in the Mako series and follows the same dual-footswitch, six-knob, three-switch format of its siblings (the R1, D1 and ACS1). What you’re getting is a multi-function modulation pedal with six algorithms that include chorus, phaser, tremolo, vibrato, rotary and filter – but, surprisingly, no flanger. 

A massive plus point, however, is the amount of adjustability you get: three different programs (effect types) for each algorithm, plus a further 11 parameters accessible via the front panel, as well as the standard Rate and Depth knobs.
