Dr J Emerald Overdrive New from Dr J is the Emerald Overdriver pedal. Loaded with features, it gives a punchy, bold, modded vintage tone, perfect for those about to rock. One valuable feature is the boost switch so that you can boost your signal for solos. The boost switch has its own control knob and is very loud, so you can customize your playing dynamics. The Emerald is true bypass, has an on switch, tone and output controls, along with a clip switch and the option to put the boosted signal before or after the overdrive. Its build like a tank for years of use and takes up minimal pedal board space. We're very excited about this new addition to the Dr J family of original effects.
