Amps & Effects Electro-Harmonix Distortion & Overdrive | Electro-Harmonix Op-Amp Big Muff Pi Fuzz Effects Pedal

With Original Late-’70S Op-Amp Big Muffs Commanding Exorbitant Prices, Mike Matthews Decided To Take The Power To The People And Reissue The Classic Pedal At A Price That Players Could Afford. The Circuitry Of The Op-Amp Big Muff Fuzz Effects—Sometimes Also Referred To As The Ic Or V4 Big Muff—Has Been Faithfully Re-Created While Several Practical Enhancements Have Been Added, Including A Compact, Die-Cast Chassis And True-Bypass Switching.

The Pedal Relies On Op-Amps Rather Than Transistors And Three Gain Stages Rather Than Four To Create Its Signature Sound. The Original Op-Amp Big Muff Has Many Devotees, Including Billy Corgan, Who Made Use Of It Extensively On The Smashing Pumpkins’ 1993 Album Siamese Dream. After Playing The New Reissue, Billy Said: “The Magic’S Still In The Box; I Can Still Get What I’M Looking For!”
