Exclusive mouthpieces with screw rim

Each mouthpiece of the JK-Exclusive flugelhorn series also can be bought as bottom part and screw-on rim. All screw-on rims can be delivered as silver plated brass, high gloss gold plated or as white plastic, e.g. to give allergic costumers an alternative or to make possible comfortable playing in winter.

The rim contours -1, -2, -3, -4 and -N are transferable to all diameters of the Exclusive series.

For instance, the bottom part 5C can be matched with the rims 5-1, 5-2, 5-3 etc. Each screw-on variant can be manufactured as one-piece mouthpiece too.
