PCT No. PCT/GB92/01194 Sec. 371 Date Jan. 4, 1994 Sec. 102(e) Date Jan. 4, 1994 PCT Filed Jul. 2, 1992 PCT Pub. No. WO93/01586 PCT Pub. Date Jan. 21, 1993.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).
