Forth pedal

[JWyatt1492@AOL.COM]

Hello Angelo!

    The forth pedal you speak of when engaged causes a
felted bar to block the hammers from striking the strings
but ( when regulated ) allows the hammers to strike 
rinky- tink tabs witch would then strike the strings. 
   This produces a sound that is very small and pleasing 
something like a harpsichord. Geo. P. Bent did not equip 
the "Concord" with this feature as it was his second line 
piano.  I always rebuild this attachment as it is such a nice
sound and mechanically works so well.   

   Hope this helps,
   Jack Wyatt
