RATIO - Calibrated machine heads incorporate different string gauges into the tuning equation. Low E to G - 48:1, 36:1, 25:1 and 23:1. We've balanced the gear ratios for each string, simplifying the tuning process. With RATIO®, a half turn is a half tone! Each string reacts the same to any tuning adjustment. Predictable and precise tuning on every string. The PRB-4401 is a right-handed set of RATIO® tuned tuners for BASS that utilize an in-line 4 configuration. In order to achieve higher transmission ratios, Ratio is the world's first machine head using a double-shell gear design with a hardened steel gear. Incredibly soft and super durable.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"prodcutDescriptionLong\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cul id=\"itemBullets\"\u003e\n\u003cli\u003e\u003cspan\u003eGear ratio: unique for each string position - one tone of one turn\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eRequired dowel hole diameter: 0.720\" (18 mm)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eRope post diameter: 0.547\" (13.9 mm)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eLength from string post to string hole: 0.807 in (20.5 mm)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eWeight per machine head: 3.5 oz (99.3 g)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eWeight per set of four: 14 oz (397 g)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eRope diameter up to 130 gauge\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eIncludes 4 machine heads, mounting screws and bushings\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Graph Tech","offers":[{"title":"Default Title","offer_id":41701774393423,"sku":"PRB-4401-G0","price":257.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0054\/9466\/9382\/files\/PRB-4401-G0_lg.jpg?v=1715788253","url":"https:\/\/shop.musicredone.com\/products\/graph-tech-prb-4401-g0-ratio-electric-bass-guitar-machine-heads-gold","provider":"RedOne Music Canada","version":"1.0","type":"link"}
