{"product_id":"electro-harmonix-op-amp-big-muff-pi-distortion-sustainer-pedal","title":"Electro Harmonix Op-Amp Big Muff Pi Distortion \/ Sustainer Effect Pedal","description":"Dial up huge walls of grungy sound, searing lead tones, and much more with this modern version of a classic Big Muff pedal. The circuitry of the original Op-Amp Big Muff (sometimes referred to as the IC or V4 Big Muff) has been faithfully recreated, 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, which is a huge, crushing Big Muff sound with more crunch.","brand":"Electro Harmonix","offers":[{"title":"Default Title","offer_id":27873474805824,"sku":"OPAMP","price":96.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0147\/9412\/9472\/products\/OPAMP.jpg?v=1645734300","url":"https:\/\/www.elderly.surf\/products\/electro-harmonix-op-amp-big-muff-pi-distortion-sustainer-pedal","provider":"Elderly Instruments","version":"1.0","type":"link"}
