<html> <body> Does that part of the scale seem a little overpowered?  Is it boomy?  Might be impedance...

When you play C3 loudly with the sustaining pedal down, you hear a bit of the B next to it. The problem is NOT caused by the hammer being misaligned and striking part of the B bass string - -the hammer is nowhere near the B string. In fact, BOTH strings of the B note are vibrating when the C note is played loudly. I've never seen this problem or heard of it in all my years in business.
