Featuring a separate JEFT-based clean boost stomp section with gain control, bright switch for a finely-tuned tonal palette and a Burr Brown OP2134 opamp for some of the creamiest overdrive around, the Diamond JDR3 J-Drive MK3 represents years of research for one of the best dual pedals on the market. Compact in design but sporting effect capabilities of a pedal twice its size, this tiny boost/overdrive titan is a perfect on any pedalboard for organic, searing tone that plays well with other effects in your chain.
