Expanding on the immense power of the standard reissue, the JangleBox JB3 Compression/Sustainer Pedal packs in new features and functionality for a true studio-grade effects experience. Built on a two-stage compression circuit, the JB3 is able to call on components like a dual output and a reconceived IC chip that provides the most reliable compression yet. Top it off with attractive bits like tweakable J-Boost Gain and J-Boost Bass & Treble controls and individual EQs on each side of the pedal for what might be the last compressor you'll ever need.
