All Rossi clarinets are Boehm System, hand-made in adherence to the highest
standards of quality,maintaining the now-classic design of one-piece body plus
barrel and bell.
They are available in the following pitches:

American  model
Compact and powerful. Solid dark sound, with built - in focus and  brilliance.
Polycylindrical bore.The middle  of the bore  measures 14.7 mm.  in diameter   
Barrels  for   A = 440  and  442  included. Shorter  or  longer  barrels  also  available.

French  model
Flexible and resilient, with a powerful, woody, sweet sound. Excellent projection. Bore dimensions closely resemble the American model, as do the response and intonation.
The upper part of the bore  is evenly  tapered  instead of polycylindrical. Barrels  for   A = 440  and  442  included. Shorter  or  longer  barrels  also  available.

 LR model 
Warm and clear, the LR combines a robust powerful resonance with an extremely smooth and mellow timbre. American polycylindrical bore with tonehole placement derived from the French model creates a sound which is very powerful but slightly less "direct" sounding than the American model. Ideal for players who like an A clarinet tonal quality on both their B flat and A clarinets. Barrels  for   A = 440  and  442  included. Shorter  or  longer  barrels  also  available.
