Designed for basses fitted with a two-by-two headstock, this complete set of Schaller BM4 Light machine heads weigh up to 50% less than standard tuners, improving balance and reducing head-dive.
This full set of Schaller Original F-Series BMFL 4-In-Line Bass Guitar Machine Heads has been specifically calibrated to give the tuning of models like the Fender Jazz Bass and Precision Bass a mega-upgrade.
