>>Peter Watchorn's set:
Big Germanic harpsichord, and he uses 16' and 8' pedal on some of those
preludes and fugues as well; a thrilling sound all around.<<
I should clarify one small bit of that: in book 1 it's the *pedal*
harpsichord that's "Germanic", styled after Hass principles. The manual
instrument on this recording is a non-Germanic double: copy by
Hubbard/Broekman of Ruckers/Blanchet/Taskin.
It's book 2 where Watchorn will have a Harrass copy, as was also heard
in his set of the toccatas BWV 910-916 a few years ago.
To Ray's short list of other people recording book 1 on a German
instrument, don't miss Glen Wilson's 1989 recording on a copy
(Sassmann/Kramer) of the 1728 Zell.
