On-the-fly adjustment has never been easier!. Each string position has its own calibrated gear ratio, so each string feels and responds the same to any tuning adjustment. A full rotation of any key results in a change in pitch of a full tone (more or less). From Low E to G, the gear ratios are 48:1, 36:1, 25:1 and 23:1. In order to achieve higher gear ratios, the Ratios are the world's first machine heads to use a double cased gear design with hardened steel gear. Surprisingly smooth and super strong.\u003c\/span\u003e\u003c\/p\u003e","brand":"Graph Tech","offers":[{"title":"Default Title","offer_id":41688803573839,"sku":"PRB-4221-C0","price":239.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0054\/9466\/9382\/files\/PRB-4221-C0_lg-removebg-preview.png?v=1715717755","url":"https:\/\/shop.musicredone.com\/products\/graph-tech-prb-4221-c0-ratio-2-2-electric-bass-guitar-tuners-chrome","provider":"RedOne Music Canada","version":"1.0","type":"link"}
