I have a 2004 Fender Hot rod deluxe in at the moment. Uses same asymetric (plug is not along centre line of the frame) low profile , probably Neutrik , but the sleeve contacts are proper sprung ones and the bush is plastic, not metal like the Bassman one
With the Bassman one last week. If you wedged a couple of bits of plastic under the T & R bypass contacts then the sleeve of the plug would move about in the sleeve "contact"
