<HTML>          John    I beleive that has been a standard S,S, model B plate has been changed for at least five years or longer. If I talk to Scott I'll ask him,       By the way when making a quick check of this just play chromatically from f octave 5 thru f octave 6 & listen to the quality of the tone, then do the same with the action shifted making sure it clears or is clearing the left hand string. If it is dramatically nasal and weak slide the whole action in and out.I.E. equal amounts bass and treble appox. i/8" or so and recheck.        It is possible that the hammers have been so over hardened/or shaped to death to compensate tonally for the poor placement that after moving them they will sound a bit choked and voicing will now be more affective. Often rinsing the whole hammer with acetone can wash the lacer out or farther down in the hammer and restore the tone.           Dale Erwin</HTML>
