hi Ike, nice to see you have avoided the 'Rona
if the Windsavers are plentiful and cheep and sized so you can use them
on accordion reeds then sure... but i know very very few 'monica players
that would ever bother with maintainence of any type much less
taking one apart and adding these... plus i doubt many models have the
internal clearance to use these without slapping or buzzing
ciao
