Abstract
A tremolo system for a stringed instrument includes a base plate (10) secured to the upper surface of the body (2) of the instrument and provided with a transverse slot (12) feeding into a hollow volume (6) within the body (2), the base plate carrying a pair of laterally opposed first bearing portions (20) located within the body (2) one below each end of the transverse slot (12), and a block member (22) carrying second bearing portions (24) co-operating with the first bearing portions (20) whereby the block member (22) is pivotal about an axis extending transversely of the body (2) below the upper surface thereof. A tremolo lever (30) is secured to an upper extent (26) of the block member (22) projecting from the slot (8), while resilient mechanisms (34) react between a lower extent (36) of the block member (22) and the body (2) to maintain the block member (22) in a position of equilibrium against the tension of the strings (4). Movement of the lever (30) pivoting the block member (22) alters the tension in the strings (4).
