Awesome dual purpose pedal! I gaff taped this down to my board years ago like a fool and in pulling the tape off, the finish came off. That's the only issue here.

From Jim Dunlop's description:

The overdrive section is truly "classic", adding warmth, sustain and punch, without coloring your sound. It can go from a bluesy, slightly overdriven sound to full-metal crunch with a twist of the gain knob. The MC402 also cleans up nicely when you roll back your guitar volume, making it extremely touch sensitive and responsive to picking dynamics, without becoming thin sounding. The boost circuit alone is a bonus, as it is the exact same circuit CAE has used for years to solve a wide variety of signal conditioning problems in major guitar systems. The MC402's high quality components provide quiet operation and trouble-free interaction with other pedals on your board. In keeping with the CAE tradition, the design is simple and straight forward, with a minimum of controls—only what is necessary to do the job.
