Thanks David, Although I had considered the springs it seemed moot if the specs are so far out of whack. They are strong. I guess that would at least make it "work" better. Is that what you ended up doing? It was sent with about 5/8" let off which meant control and pp was pretty much random. Thanks.

How are the damper springs? Are they excessively strong? Is it any better with sustain engaged? By weakening the damper and jack springs and restoring more normal regulating dimensions it seemed to cure it on these. Your mileage may vary. David David C.
