Hand made original "Kalamazoo Line". The B11 is essentially the same as the B3 model with a slightly different look. Works best on thin hollowbody archtops such as Guild Starfire III's, Gretsch 6120 Nashville's & others that use a floating style bridge. It can also be used on some solid body archtops that use the same style bridge such as a Gretsch 6129T Silver Jet. The only holes that need be drilled are the three at the bottom of the guitar where the hinge attaches to the body. Similar to the B3 but with a more minimalist appearance. Overall length 7 and 11/16 inches. Overall width 3 and 11/16 inches.
