This is a bridge for a double bass. 〇 It was originally fitted to a 3/4 size Romanian double bass. It's practically unused, as it was immediately replaced with a bridge with adjusters. 〇 French style. The material is "aged maple." 〇 The string grooves are carved at 2mm. 〇 While there may be variations depending on the manufacturer and the individual instrument, it may not fit your double bass directly. However, it should be usable with adjustments using a file, etc. - Size: 171mm x 150mm - Material: Maple 〇 No claims and no returns accepted. Thank you for looking.
