Jazzy switch not working

Got my SQ VM Jazzy yesterday and did a slight relic job plus setup with Tune-o-matic..sounds grrreat.
Have a Mustang bridge also but the TOM sounds much better, though I still have to file down the notches a bit..

well, I did a standard wiring but the rhythm switch doesnt work properly..I can hear something but veeeeeeery silent, is there a ground soldering missing on the switch??

I noticed a difference in the schematics..in the original Fender one, the cap has a connection to ground ( pot case), in the Duncan plan not..

Well spotted!

ok, I desoldered this ground connection but now the switch activates the neck pickup, like a toggle, very strange..
maybe broken..IÂ´ll just replace it..

You need the cap connected to ground for the tone control to work as a tone control.
