Deceptively simple but immense in presence, the JangleBox Compression/Sustain Pedal captures the legendary tone of the original with an updated design and host of premium components. Sporting a few subtle adjustments like a more reliable IC chip and even-keeled power polarity, this new iteration also brings a svelter chassis to the table with a streamlined interface of gain/attack knobs and a three-position brightness switch. A clear avenue back to the chiming, crisp sound made famous by the Beatles, this is a Cadillac option in the realm of compression.
