Muting high treble

[Jay Mercier]

I thought this phenomenon is just the opposite.  The pitch sounds 2-4 cents 
sharper when the strip mute is in, compared to when it's out and after the 
unisons are tuned. Isn't this common and tuners must compensate?  The pitch 
difference is obvious when comparing a muted trichord - hearing just one 
string compared to the overall pitch after tuning its two unisons.
