Louisa you were right on the money.  I grounded the metal trim ring and all is quiet....very quiet.  Thank you.

Hopdybob......thanks for the suggestion.  If I end up redoing the wiring for any reason I'll exercise it.   For now all is quiet and the guitar sounds great so I'm going to leave it well enough alone.

FYI....for anyone interested the L-90 bridge and L610 neck is a great combination.  I was looking for great blues and jazz tones from the neck and not harsh but ballsy and rich distortions from the bridge. With this combo I got just what I wanted.  Very pleased.

Thanks again
