Huh? I thought the machines used were non-Ampex, forgot the brand, or was that just the "vintage
restored machine" used for the CD remaster? I forgot if it was a Magnecorder or that other non-Ampex
pro machine of the era (pre-Scully). The CD reissue that first got the speed thing right, if I
remember the press reports correctly, was done on one of these machines. But at the same time,
anyone I know who ever worked Columbia 30th St. or 52nd St. talked about Ampex machines. Then that
begs the question, why would Sony dig up one of these kind of oddball old machines when old Ampex
300-3's (complete machines or piles of machines easily made into the right configuration with a
Sony-sized budget and a couple of days at John French's place) were and are all over the place.
Mark Wilder of Sony, who I think discovered and fixed the problem, played a demo at an AES maybe 6
years ago in NY, centered around a panel discussion about Ashly Kahn's book about "Kind of Blue"
(one man's opinion here -- I find that album good listening but of highly inflated importance in the
general scheme of jazz, but it is fun to listen to once in a while and did sell a lot of copies so
props are due). The pitch shift is very subtle but I can definitely see why a generation of
musicians wanting to play along were scratching their heads, especially if they initially tuned to a
StroboTuner or tuning fork. I think the net time difference for a whole 20+ minute side is less than
a minute (ie less than 5%) but a trained musician with perfect pitch can detect 1% out of key.
