Abstract

A pitch adjustment device for selectively adjusting the pitch of multiple strings of a stringed musical instrument from the open pitch (normal unadjusted pitch) while playing using a single lever, wherein the tension and pitch of different strings can be adjusted by different and adjustable amounts for each adjustable string. The device comprises a support frame configured to be mounted onto the stringed musical instrument and a string puller rotatably coupled to the support frame and rotatable about a first axis. At least two pitch adjusters are attached to the string puller. Each pitch adjuster has a string support for securing a respective adjustable string and is adjustable to adjust the respective string support to a plurality of different radial positions from the first axis. A lever coupled is the string puller such that pivoting the lever rotates the string puller relative to the frame about the first axis.
