4 Op-Amp Big Muff Pedals (EHX, Wren and Cuff, Greer, Keeley)

A thorough comparison of four 'remakes' of the Electro-Harmonix Version 4 'Op-Amp' Big Muff, which EHX released in the late 1970s with the previous versions' transistors replaced with op-amps or 'integrated circuits'. Not a popular pedal at the time, it re-emerged in the 1990s off the back of its extensive use by the Smashing Pumpkins on 'Siamese Dream' and other recordings.

Various boutique pedal manufacturers have released clones in an effort to sell to people who can't afford to pay the high prices for the original, and in 2018 Electro-Harmonix released their own reissue in 'nano' pedal size.
