A unique solution to a common bridge problem, this spruce device attaches beneath a guitar bridge. An adjustable spruce “pressure post” rests against the tail block, providing leverage to flatten the soundboard.

The spruce block is 3/4″ (1,9 cm) x 1-5/8″ (4,3 cm) x 3-3/8″ (8,6 cm) tall. The 1/4″ (0,6 cm) diameter tension rod is 9″ (23 cm) long. The mounting post has three different positions to accomodate a variety of bridge styles.

This spruce device attaches beneath the bridge via an inlaid screw (a white pearloid dot is included to hide the bridge screw). An adjustable spruce pressure post rests against the tail block, providing leverage to flatten the soundboard. Better bridge contact and alignment can also enhance sound projection.

Tech Tip: We recommend the brass pin Bridge Doctor (SM3695 / #50092) for 12-string guitars.
