JK „Classic“ trumpet mouthpieces are an extension to the Exclusive Series. According to the today's sound expectations in classical music, these models are offering a deeper volume in combination with a much focused sound. The rim and cup diameters as well as the rim shape are identical to the JK Exclusive models. This enables the player to the switch easily between both mouthpiece lines.

Exclusive mouthpieces with screw rim

Each mouthpiece of the JK-Exclusive trumpet, flugelhorn and cornet 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.

Example

Trombone screw rims

Beside the standard rim, for the JK-Exclusive trombone mouthpiece series as standard we offer three different screw-on rims per cup diameter which fit all to the bottom part of the respective series number. All screw-on rims can be delivered as silver-plated brass, high gloss gold plated or as white plastic.
