Rocktron's Reaction pedals feature metal enclosures built to absorb maximum punishment while taking up minimal pedalboard space and include True Bypass switching. 

A rock-solid choice for basic phasing needs, the Reaction Phaser is a super simple pedal with a fixed depth and and mix, you just set the Speed control of the effect and you're ready to go. Slower speeds allow a more subtle, classic sound for funk or psychedelic rock while fast times are capable of pushing your tone into ray gun territory for more experimental outings.
