Check it out... http://www.pickettbrass.com Does anyone have any experience or opinions? After I buy my new horn I'm considering fooling around with my current Bb. My new horn will be anywhere from a fairly medium, all-around horn to a very bright, lead-type horn. It depends on what works best when I get to trying new gear. Whatever happens, I'm planning keeping my Yamaha, which is a very good, solid horn. But, since it will be my spare horn I feel better about customizing it. I'm planning on a new lead pipe(probably GR, but also considering Blackburn and Pilczuk) and I thought adding all the heavy weight accessories might be interesting. I did a search about heavy weight bottom caps but these are a little different. So, any thoughts on these or similar options?
