what are the qualities of a gibson clarinet?

Answer 1

I've never played a Gibson clarinet and I'm not too familiar with the quality of their clarinets, but according to their site:

Clarinet features a durable ABS Bakelite body, adjustable thumb rests, metal Tenon rings, nickel-plated brass and French-style sculptured keys with Italian felt pads. Kit includes B-flat clarinet, Rico reeds, cleaning swab, cork grease, maintenance manual and plush-lined, soft carrying case.
