First choice for the vintage Lloyd Loar look. Retrofit your F-5 with this fine quality ebony Lloyd Loar reproduction bridge from respected luthier Randy Wood. Vintage touches include small 3/8" knurled thumbwheels for height adjustment, and the authentic 1921 patent date stamped on the bridge base. The compensated unslotted saddle is delicately machined like the old bridges, and the base is ready for fitting to your mandolin's top curvature. Minimum adjustable height is 7/8".
