But if you do go for that VI, be ready to shell out your money!! Those horns are very over priced, and most of what you pay for is the Mark IV name, because so many of the great players played VIs(of course, many greats played other horns!) If you are going to pay the big bucks for the horn, buy it in person where you can play test it first, for intonation, etc. Another thing to be ready to pay is for an over haul, all new pads, etc which is something lots of vintage horns need when you first get them. Also, make sure that it isnt a relaquer, those hurt you if done poorly. make sure the serial numbers match, that it hasnt had any huge repairs before, and that it isnt falln apart. That goes really just for the Mark VI< but any Vintage horn. The best advice anyone can give you is to look into and try as many different types of horns as you can and get the one that is right for you. Just dont be narrow-minded and think only a VI will do.
