Abstract
Abstract This invention relates to an acoustic guitar bridge comprising a body shell (1) for attachment to the body of a guitar, an adjustable saddle member (12) for supporting the strings of the guitar and an adjustable support member (4) for engaging and supporting the saddle member along its length, the support member being housed within the shell and the saddle member being arranged in a slot (3) in the shell, those members being mounted for movement, relative to the body shell, in respective directions lying transverse to each other and engaging each other through surfaces at least one of which is inclined to the direction of movement of the support member whereby movement of the support member varies the height of the saddle member relative to the body shell.
