I know this post has been dormant, but I just reread it and had to comment on the whole plastic sax thing. I don't think Coltrane played a plastic sax, but I know for a fact Parker did. You can here it on a disc called The Quintet, Live at Massey hall, where he plays with Roach, Mingus, Powell, and I believ Gillespie, but I would have to check the linears. Coleman also dabbled in playing a plastic in the sixties, although I cannot recall which albums. BTW I personally play a vintage Martin, but a Rigel to me sounds like a quentisential jazz mando, if such a thing can exist. I would play one in a heatbeat if I could afford, especially, the CT-110.
