"Legendary" Mark VI Tenor vs Vintage Student Buescher - do you need a pro horn? 

I have the same Buescher horn circa 1970....has a brighter sound bc of my syos mpc...I swear by it..

At the pro end of things, tho, the choices of your colleagues do influence their opinions of you. If Selmer et al suit you, you're more likely to suit them. If Buescher et al suit you, there _may_ be a question. Even if you have a horn that was considered a pro sax back in the day - there's a judgment of present day practice implied in that. If you bring a loaner student Buescher to a gig, that's one thing. If you bring a 1936 Aristocrat to _every_ gig, that's quite another. Maybe even a thing above and beyond your playing. Like: who are your teachers? who are your idols? whom do you respect among your peers? are you schooled or self-taught? what does "pro" mean to you?
