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

The Reaction Compressor includes controls for Attack, Sustain and Level, so you can use it to increase your picking attack for funk strumming, create endless sustain on melodic sections, or give your solos a clean boost. A great compressor for everything from country picking to blues rock.
