This is a $99 overdrive pedal. It gives your guitar an overdrive effect. It's really easy to use because it has three knobs and one toggle.

The JHS Pedals 3 Series Overdrive offers a wide range of overdrive sounds within straightforward design aesthetics. 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.
