[pianotech] WNG jack don't come back no more, no more, no more.....

[J Patrick Draine]

Hi Ed,
What is the gram resistance of the jacks? My thought is it may be too high.
Check the WNG documentation on this, and/or give Bruce Clark or Mike C. a
call at M&H. Of course they may be at NAMM at this time, but worth a call.
