Dial in your overdrive and distortion with the Electro Harmonix EHX Tortion JFET overdrive pedal. This versatile guitar pedal offers a preamp with controls for volume, pre-gain level, pre-amp gain saturation, and a three-knob EQ for bass, mid, and treble. Click the boost switch to change from the JFET controls to a simple yet classic volume and gain setup, or hit the bypass switch to shut everything down and get back to your clean tones.
