Hi Jon,

Using a gang wedge or muting strip in the temperament section of the
piano.  Does this not course a problem with worn hammers as it forces
the strings over so when you play the note it hits the crown of the
grove and not the groove.  Having never used one I am unaware of the
potential problems.

Could you also clear up a falesy which seems to be quite general in the
u.k. with ETAs and muting strips.  Most tuners in the U.,K. take
approximately forty minutes to an hour to tune an up right piano which
has been tuned on a regular basis every six Moths.  The fallesy or not
is that we are led to believe that someone using an ETA and a muting
strip takes one hour and thirty minutes to do the same job.  Is this
true or false?  and is it the fault of the ETA or a muting strip?  Do
tuners in the U.S. who use ETAs use a paps wedge?

Regards,

Barrie.
