Dubbed the Triangle Big Muff because of the layout of its Volume, Sustain and Tone controls, this is the one that started it all. The Electro-Harmonix Triangle Big Muff is a faithful re-creation of the original circa 1969 circuit now housed in a pedalboard friendly, die-cast chassis.Electro-Harmonix founder, Mike Matthews, says: "The Big Muff Pi is the pedal we are best known for so I wanted to commemorate EHX's 50th Anniversary (1968-2018) by re-releasing V1, the very first Big Muff. Original pedals are now selling for hundreds of dollars and this reissue absolutely nails that creamy, violin-like sustain and musical tone at a price a working musician can afford."The Triangle Big Muff features the following nods to convenience: an LED to indicate effect status, true bypass switching and the option of being powered by a 9-volt AC adapter.The authentic V1 Triangle Big Muff reissued in a nano-sized chassisEffect status LEDTrue bypassVintage look and graphicsOrder your Electro-Harmonix Triangle Big Muff Pi Distortion/Sustainer Guitar Effects Pedal today..
