Addendum: As
mentioned in this review and the review of the MK low F, I pointed out
that they had what appeared to be dents on the head of the whistle that
I speculated occurred during the manufacturing process. However, I was
nonplussed to discover two more of these "dents" show up on the whistle
reviewed above, without any impact occuring to the instrument! I
noticed that these dents were all in the same location around where the
female part of the tuning slide joint ended on the inside of the
whistle head. Naturally I shot an email off to Misha Somerville, and he
informed me that this phenomena did occur on earlier models of his
whistles, as the aluminum proved not to be thick enough at that point.
He stated that while unsightly, he was unaware of these dents or
buckles rendering a whistle unplayable or effecting it's tone. He also
assurred me that they had fixed this issue on their newer models. As
the above reviewed whistle is my main go to low D, I decided to order a
new one incase this one ever did structually fail. (as I had purchased
the above low D second hand, it was not covered under any manufacturers
warranty) The head joint on my shiny new black MK low D is noticeably
heavier than on my green one, most likely due to the structural
reinforcement added to correct the above problem. Unfortunatley, while
the whistle still looks, and plays as good as my first green one, the
tone is slightly less open/resonant and a little darker, perhaps also
due to the heavier head. It also seems to have just slightly more
backpressure as well. It is still a great whistle, but my green MK
remains my favorite.
