While plenty of people have built clones of the Big Muff Pi with various bells and whistles, Electro-Harmonix keeps things pretty traditional.  That ends now.

The Deluxe Pi looks and sounds pretty slick.  It gives you the sound you’re used to, but with a lot more options that can add character and make it a more usable full-time pedal.

From EHX:

Now, we’ve added extras for those who crave more sound shaping control. The Deluxe Big Muff Pi delivers all the classic sounds of the original NYC Big Muff plus a lot more. It includes:

• Foot-switchable Midrange Section with variable center frequency and boost/cut knobs.
