"Bosendorfer Bass/Tenor Break"

[David ilvedson]

Of course you've checked to see that the tri-chord damper is 
lifting enough to clear those strings?  Try a little sugar 
coating at the strike point and feel for any hard spots without 
doing any real changes.  I generally try to make the tenor sound 
more like the bass to even the break out.  Consider moving the 
action in and out just a bit to see if there is any improvement.
