Whether or not you believe the Selmer Mark VI is the best saxophone model ever made (most of your favourite musicians do), it is certainly the most legendary and easily the most imitated one. Virtually every new saxophone made since the end of the Mark VI run in the early 1970s has been a copy of this design. Both mechanically and acoustically, these are superlative instruments. There were many small changes made over the 20-odd years these beauties were produced, and the earlier ones do play differently than the later ones, but they are all fantastic horns. I haven't met one yet that wasn't an excellent instrument after the necessary setup and repair work.
This particular horn is still wearing 90% of its original lacquer with wear at all of the usual spots. The neck and body are clean and straight save for a couple small resolder jobs over the years (typical). This particular VI also has the optional high F# key, which makes for a beautifully easy high G as well as a nice transition into F# from the palm keys. Included is the original case and end plug, which gives a small idea of the care that has been taken with this one over the years. This is a turn-key instrument that seals well and is mechanically tight - ready to go and won't need an overhaul or any major work for many years to come. It plays big and crispy and feels perfect under the fingers.
An instrument is a personal choice and everyone likes something a little different, but there is a very good reason these instruments have the reputation they do and have been the choice of so many artists throughout the years.
