TonePros KB3L locking guitar tuners are 15:1 high-ratio 3 on a side machines with the vintage buttons of the B3 Series in a locking format. B3L series tuning machines are high tech yet low profile tuners that lock from the top of the post with simple hand pressure. No tool is needed. Special hardened steel post tops on each tuner provide an attractive and easy-to-use locking mechanism.
