I have a harness with two Blacktop Filtertrons connected to it with the plastic quick connects which Gretsch is now using. I was thinking of popping the pickups off of the harness to try them in another guitar but can't seen to get the connectors to release. Am I missing something? Is there some small trick I need to know? I'm afraid if I use too much force on the clip which holds the male plug in place I'll break the connector or pull the wires from the fitting. Appreciate any advice.
