Electro harmonix Triangle Big Muff Pi

Reissue of the 1969 Big Muff, better known as the Triangle Big Muff (so called because of the layout of its Volume, Sustain and Tone parameters), the EHX Triangle Big Muff Pi Distortion/Sustainer integrates a faithful re-creation of the original circuit, housed in a pedalboard-friendly die cast chassis.
Original pedals are selling for hundreds of dollars and this replica absolutely reproduces the legendary, creamy, violin-like sustain and musical tone at a price a working musician can afford.”

The Triangle Big Muff Reissue features an LED to indicate effect status, true bypass switching and the option of being powered by a 9-volt AC adapter. It also comes equipped with a 9V battery.
