the mass of the brass is a gass

[Farrell]

Wudya charge her?

And don't belittle those old nasty Acrosonics too much - they were among the
best of those crappy little pianos - maybe next best to the Yamaha spinet
(just serviced one today - dog-gone nice little itty-bitty piano).

So now why did mass make a difference down there? I thought mass only became
improtant in the high treble?
