Dan is great. He's helped out a lot in terms of advice and instruction on some of my projects. And for a few years I've played on an intermittent basis with someone here who has bought a couple of tubas from him -- including a Marzan BBb that has an incredible sound. It's kind of like what the voice of God should be, channeled through a tuba and delivered with complete "surround sound".
