I might buy an old Selmer Brevete from a friend ( he just got a Buffet E12 (?) think thats it), This is a 1930s clarinet, and not in bad shape. The keys have some play to them, and can only be fixed with a complete rebuilt (i mean so that it doesn't move at all, it plays wonderfull and the sound is great). I will get a Brand new Buffet mouthpiece with this, so how much is it worth? If i get it for $50...maybe $100 is it worth it? Sorry, but like many of you here (i can actually say it here, and have people understand.....its wonderful) a sax player, just started clarinet. I might as well ask it here too, what are the most common mistakes alto to clarinet "switchers" make?
