Dobro capo

摘要

A low profile capo for a stringed musical instrument having elevated strings such as dobro or the like. The capo comprises an elongated, rigid, bar-like frame adapted to be disposed over the top of the strings above the instrument neck. A pair of integral, elongated frame ridges which are offset from the recessed bottom frame surface provide definitive metal-to- metal contact with the dobro strings. Since the frame ridges establish a definitive point of contact across the strings above the neck, the strings are allowed, if not forced, to resonate at an elevated frequency without dampening of the resultant sound amplitude or quality. A cooperating compression arm assembly is adapted to swing in or out of operative position about a pivot point defined upon one end of the frame. The arm comprises a coaxially encircling, resilient sheath, preferably formed of rubber, polyethylene or the like, which is adapted to firmly engage and substantially surround at least a portion of the strings. The arm is deployed by rotating it into substantial alignment with the frame under the instrument strings, whereupon an associated clamp is closed to firmly urge the arm, and the surrounding sheath, upwardly towards the strings for constraint against the capo frame.
