Choose the 3\/4-size or 1\/2-size orchestra set to match your instrument. Both configurations contain E, A, D, and G strings with ball ends and support bowed and plucked playing.\u003c\/p\u003e\n\u003cp\u003eFor an upright bass replacement set, start by confirming your instrument's size. Select the 3\/4 option for a bass requiring that designation, or the 1\/2 option for the corresponding smaller instrument. Players preparing for orchestral rehearsals, jazz sessions, or mixed playing can consider these strings for arco, meaning bowed technique, and pizzicato, meaning plucked technique. Keep the size selection consistent when reordering your preferred setup.\u003c\/p\u003e\n\u003cp\u003ePirastro assigns separate article numbers and published tensions to the two configurations, helping teachers, performers, and instrument technicians specify replacements accurately. Both retain the same core and winding materials, orchestra tuning, and medium designation. Compare the size guide below, then confirm compatibility with your instrument's setup. Record the selected article number so future orders identify the intended version clearly.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo instrument sizes:\u003c\/strong\u003e Select 3\/4 or 1\/2 to match your bass.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSynthetic multifilament core:\u003c\/strong\u003e Uses a core formed from multiple synthetic fibers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChrome steel winding:\u003c\/strong\u003e Maintains consistent winding material across the four strings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBowed and plucked applications:\u003c\/strong\u003e Supports players using both arco and pizzicato techniques.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete orchestra configuration:\u003c\/strong\u003e Replaces E, A, D, and G together.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall-end fittings:\u003c\/strong\u003e Provide the same attachment style in both sizes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e3\/4 and 1\/2 Size Differences\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e3\/4 Size:\u003c\/strong\u003e Manufacturer article 441020; total published tension of 255.3 lb.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1\/2 Size:\u003c\/strong\u003e Manufacturer article 441050; total published tension of 215 lb.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Pirastro\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Obligato\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstrument:\u003c\/strong\u003e Double bass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize Options:\u003c\/strong\u003e 3\/4 and 1\/2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge:\u003c\/strong\u003e Medium, also designated Mittel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTuning:\u003c\/strong\u003e Orchestra, E-A-D-G from lowest to highest\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Material:\u003c\/strong\u003e Synthetic multifilament fiber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWinding Material:\u003c\/strong\u003e Chrome steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type:\u003c\/strong\u003e Ball\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3\/4 String Tensions:\u003c\/strong\u003e E 68.1 lb; A 65.5 lb; D 62.2 lb; G 59.5 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1\/2 String Tensions:\u003c\/strong\u003e E 55.6 lb; A 58.2 lb; D 51.6 lb; G 49.6 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3\/4 Peg-End Colors:\u003c\/strong\u003e E dark green; A black; D rust red; G brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1\/2 Peg-End Colors:\u003c\/strong\u003e E dark green\/golden yellow; A black\/golden yellow; D rust red\/golden yellow; G brown\/golden yellow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTailpiece-End Colors:\u003c\/strong\u003e Rust red\/black\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's In the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOne E, one A, one D, and one G string in the selected instrument size.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pirastro","offers":[{"title":"3\/4","offer_id":50815756927173,"sku":"PIRA-1BBS","price":357.3,"currency_code":"USD","in_stock":true},{"title":"1\/2","offer_id":50815756959941,"sku":"PIRA-1BBS12","price":348.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/3085\/3829\/files\/1-pirastro-1bbs_8d5ebc87-0f1f-499f-a11c-5daecd19b527.jpg?v=1793113914","url":"https:\/\/avlgear.com\/products\/pirastro-obligato-double-bass-string-set-medium","provider":"AVLGEAR","version":"1.0","type":"link"}
