All tuning machine rollers are NOT created equal! As an authorized Rubner dealer/reseller, we are proud to introduce the Superior Series from Thomas Rubner GmbH. Thanks to the proprietary Rubner Roll end bearings, these wonderfully crafted machines offer an unsurpassed precision and smoothness of tuning. In addition, decorative inlays matching the handles make the already beautiful Rubner tuning machines even more attractive. We are currently stocking a great selection from which to choose. Or if you don’t see a style that strikes your fancy, any standard Hauser-style, straight-plate or single-machine set of Rubner tuners can be upgraded with Superior Rollers as a special order.
