  • Upper manual too soft

    Just got an M3 and checked out all the tubes plays and looks great for a '56. Why is the upper manual softer than the lower manual

  • #2
    On a properly working M3, when the percussion is ON, the upper manual overall drawbar volume drops slightly by design. Turn the percussion off and try it with the same upper/lower drawbars. There is a simple modification to eliminate this volume drop when the percussion is on.
