Front duplex noise

[Doug Mahard]

Thanks Antares and Brian,

I kind of had a hunch at the time of my muting that this might not be such a
great idea.  However, I settled on letting my ears lead the way and on the
Young Chang I liked the "cleaner" sound.  Maybe the customer won't like it
and in that case I 'll retrieve my strip mute.  She doesn't like a bright
sound anyway, so she might be overly joyed about the change.  This is a
church instrument.

On the S&S M it didn't make a noticable improvement to my ears to warrant
muting that front duplex.
