Hi there, I started bass clarinet few months ago. I bought a used Bundy from my repairman. He also gave me a student mouthpiece. Since I've been playing tenor sax for a few years and I use 6 to 7* tip opening on it, that student bass clarinet mouthpiece is too closed tip for me and has lots of resistance. I tried a Vandoren B45 and B46 at the store. They sound free blowing enough for me. I had squeak here and there more than my student mouthpiece but the store agent was saying I just started that mouthpiece so if I buy it and take it home and practice, after a while I will be comfortable without squeaks. Then I started looking into forums and try to find a good used mouthpiece in the range of 100 to 200 dollars that is free blowing, has a nice sound, and is good enough till I become an intermediate player. I didn't have much luck. Either they were too closed tip (Fobes Debut) or too expensive (Grabner CX_BB_90). I think I will be fine with a tip opening of 185 to 200. I like to play solo over my own composition I do in computer. I make new age and smooth jazz stuff. I appreciate your help. Thanks, A.
