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

Offering a classic octave down effect, the Rocktron Reaction Octaver is a rock solid way to beef up your tone. High and Bass Filter controls give you the ability to adjust the treble and bass in the effected signal, and a Blend control let's you dial in the exact amount of processed octave sound you want heading to your amp.
