Have you ever felt your uke was just pitched too low No problem. Simply clamp on the On-Stage GA200 Ukulele Capo and play in any key you want. The GA200 works just like a full size spring-loaded capo but is sized for mandolins and ukuleles (soprano, concert, tenor, and baritone). Diecast zinc alloy provides the necessary rigidity, while silicone padding provides uniform pressure and protects the neck/fingerboard.
