Nickel. Tremolo system for flat or archtop guitars. Easy to install - no routing necessary! The frame is mounted at the end of the body like a trapeze tailpiece. Two additional screws attach it to the top. The string holder is clamped to a very solid spring steel sheet and can be moved up and down using the stylish tremolo arm. Simple but effective! Long version (173.5mm), incl. tremolo arm and screws.
