heath said:It won't do anything other than double the cost and add a lot of weight to the horn, which in the case of a soprano is going to be a real pain.
That is why the Mark VI is still the best. With the added weight of the big palm keys, the detachable necks, the large lower stack mechanism, the high f# ----and lordy the high G key (both easy to play on the VI)-- and the fork e/f mechanism the "new" sopranos are just too darn heavy. Kill your right hand and thumb and then you try a strap which messes up your embouchure or your neck position. Sometimes progress is meaningless. I held a new B & S Sop the other day-- felt like a bari!!!!
But most of all they have the best tone/sound. Don't believe me THEN listen to and ask a soprano virtuoso-- Bob Sheppard
