Matthews Effects' The Chemist Atomic Modulator is a do-it-all modulation lab in a guitar pedal with an analog-emulation chorus, a mind-altering phaser, and an organ-style polyphonic octaver. The fun starts with two rows of identical controls, allowing you to switch between the top and bottom row with the push of a button.
