The MXR M-66 Classic Overdrive pedal, also known as the MXR CL1 Classic Overdrive, is designed to deliver massive driving tone at an affordable price. Housed in a rugged die-cast enclosure, this pedal is built to withstand the rigors of live performance. The pedal features a tone control that allows for sound shaping, providing a wide range of tones from Texas blues to thrash metal leads. The output and gain controls offer precise control over the tone and volume, adding sustain and gain without coloring the guitar or amp's tone. The pedal is powered by a 9 VDC, 4mA power supply.
