{"product_id":"44025","title":"Electro Harmonix Op Amp Big Muff Pi","description":"\n\u003cp\u003eA faithful recreation of the famous Op Amp Big Muff Pi. The pedal relies on op-amps rather than transistors and three gain stages rather than four, to create its signature sound. It's a sound that's been described by noted Big Muff collector and historian, Kit Rae, as: “a huge, crushing Big Muff sound with more crunch… great for grungy, wall-of-sound distortion, heavy rhythm playing and heavy leads.” Made famous by The Smashing Pumpkins.\u003c\/p\u003e\n\u003ciframe width=\"480\" height=\"270\" src=\"https:\/\/www.youtube-nocookie.com\/embed\/xmUZ6nCFNoU?rel=0\u0026amp;showinfo=0\u0026amp;modestbranding=1\" frameborder=\"0\" allowfullscreen\u003e\u003c\/iframe\u003e\u003cp\u003eVideo: \u003ca href=\"https:\/\/youtu.be\/xmUZ6nCFNoU\"\u003ehttps:\/\/youtu.be\/xmUZ6nCFNoU\u003c\/a\u003e\u003c\/p\u003e\u003ch2 class=\"itemspec\"\u003eProduct Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eItem Number:\u003c\/b\u003e 44025\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMake:\u003c\/b\u003e \u003ca href=\"\/search?q=vendor%3AElectro+Harmonix+AND+tag%3Avisible\"\u003eElectro Harmonix\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eModel:\u003c\/b\u003e \u003ca href=\"\/search?q=Op+Amp+Big+Muff+Pi+AND+tag%3Avisible\"\u003eOp Amp Big Muff Pi\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCondition:\u003c\/b\u003e \u003ca href=\"\/pages\/gear-condition-key\" class=\"fs-product-condition fs-product-condition-verygood\"\u003eVery Good\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFinish:\u003c\/b\u003e Orange\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCategories:\u003c\/b\u003e \u003ca href=\"\/search?q=tag%3Aeffects-and-pedals+AND+tag%3Avisible\"\u003eeffects-and-pedals\u003c\/a\u003e ⇒ \u003ca href=\"\/search?q=tag%3Afuzz+AND+tag%3Avisible\"\u003efuzz\u003c\/a\u003e ⇒ \u003ca href=\"\/search?q=tag%3Apedal+AND+tag%3Avisible\"\u003epedal\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFunction:\u003c\/b\u003e \u003ca href=\"\/search?q=tag%3APedals+AND+tag%3ADistortion+AND+tag%3Avisible\" class=\"btn btn--small\"\u003eDistortion\u003c\/a\u003e \u003ca href=\"\/search?q=tag%3APedals+AND+tag%3AFuzz+AND+tag%3Avisible\" class=\"btn btn--small\"\u003eFuzz\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eYear:\u003c\/b\u003e 2026\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMade In:\u003c\/b\u003e United States\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMPN:\u003c\/b\u003e 44025\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eModular Grid:\u003c\/b\u003e Pedals \u003ca class=\"btn btn--small\" href=\"https:\/\/modulargrid.net\/p\/electro-harmonix-op-amp-big-muff-pi-fuzz-pedal\" title=\"View Details\" target=\"_blank\"\u003eⓘ\u003c\/a\u003e \u003ca class=\"btn btn--small\" href=\"https:\/\/modulargrid.net\/p\/modules_racks\/add\/15176\" title=\"Add\" target=\"_blank\"\u003e＋\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDimensions*:\u003c\/b\u003e 70 mm wide 114 mm high\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePower*:\u003c\/b\u003e ? mA \/ 9 V DC \/ Negative Center\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003e* User contributed details\u003c\/em\u003e\u003c\/p\u003e","brand":"Electro Harmonix","offers":[{"title":"Default Title","offer_id":67610965770476,"sku":"44025","price":149.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2604\/0858\/files\/IMG_5967.heic?v=1790926095","url":"https:\/\/foundsound.com.au\/products\/44025","provider":"Found Sound","version":"1.0","type":"link"}
