The R13 has nickel plate keys and is mainly aimed at the American and U.K. markets with pitch at A440, whereas the RC and RC Prestige with silver plate keys and pitch nearing A442 were mainly designed for Europe and Japan. After many years of producing oboes Howarth has recently introduced a professional clarinet. It has been designed in their workshop by Jon Steward and built to his specifications by Peter Worrell in the factory in West Sussex. Other pitches are available on request. The tone holes are undercut throughout.
Gold plate is also available on request.
2nd top trill hole set forward to avoid water. Adjustable thumb-rest with large plate, fitting close to the body. All clarinets are supplied with a quality mouthpiece made to Howarth specifications.
