Electro-Harmonix XO Little Big Muff PI DistortionGuitar Effects Pedal.

After extensive research into what made the 1970 Big Muff such aspecial and legendary pedal,
Electro-Harmonix came up with a new addition to its Big Muff family:The Little Big Muff.
Housed in a compact, die-cast box with smooth corners, The Little BigMuff presents the classic, true-to-heritage,
1970 tone that falls somewhere between the current U.S. Big Muff andthe Russian Big Muff. Its long,
silky smooth sustain proves that celebrated sound can indeed comein small packages.
With a familiar control layout and a pedigree you can trust, thislittle brother kicks total butt.
