Muting high treble

[David Love]

I think you are better off tuning unisons as you go anyway.  If you are
setting the temperament aurally and need to use a mute strip for the
temperament octave (or two) then pull the unisons after setting the
temperament and tune unisons as you go the rest of the way.  I think it
makes for better stability.
