You can never have too many overdrives, and the JHS Pedals 3 Series Overdrive is the ideal choice whether it's your only overdrive or 10th one! You can achieve anything from boost, transparent low gain, to huge amp-like medium overdrive sounds. The simple knob functions give you control over the Volume, Body (or EQ), and Drive. The Gain toggle gives you a choice between more saturated and compressed or more open and crunchy dynamics. This switch plays a big part in how the pedal responds to your playing and touch as a player. The JHS Pedals 3 Series Overdrive runs on 9V DC Negative Center power and consumes 12mA.
