Chuck Norris decided to make a saxophone, they call it the Mark VI.
Well….. that may or may not be true. It could have been made by Selmer Paris from 1954 to 1973.
The horn can really sing, so it has become a legend. Not all of them do, and some are in bad shape, but the ones that do play can play great.
The Mark VI’s needed to be adjusted by hand and that led to a lot of variation between the horns. This actually happens with a lot of professional saxophones.
People seem to prefer the earlier serial numbers, but that should not be the only factor you consider!
Some people really like how the Mark VI feels- the keys, mechanics, etc. This can also be adjusted though. Since the Mark VI has probably been played for a while it can be worn down. Check the pads, joints, springs, all that. These parts can be in disrepair if less than perfect care was taken of the horn.
If a Mark VI looks too shiny/new it may be have been re-lacquered. This brings down the price of the horn, since it’s not original.
The Mark VI can be a great horn if it’s a good one and in good repair. They’re not being made anymore- so their value will always go up while pretty much any other saxophone will lose value after time. You have to decide whether a particular Mark VI is worth it for you, it could be. But some modern horns will definitely sound and play better than a Mark VI that wasn’t a great one.
