This instability and “grit” are not manufacturing defects: they are inherent behaviors of high-gain tube circuits and form the core of this unit’s unique sonic character.\u003cbr\u003eIf you are looking for digital transparency or a sterile, noise-free sound, STIGMA is NOT the right tool for you.\u003c\/p\u003e","brand":"Noir Synthétique","offers":[{"title":"Default Title","offer_id":52633647153426,"sku":null,"price":530.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0905\/5145\/1922\/files\/stigma-eurorack-tube-processor-front-1782x2048.jpg?v=1787414043","url":"https:\/\/noirsynthetique.com\/products\/arcaico-stigma-dual-tube-stereo-processor","provider":"Noir Synthétique","version":"1.0","type":"link"}
