My friend has a Fender Squier Jazz Bass (bought used sometime ago) that has reached the end of the truss rod nut travel and I was wanting to try the washer trick to give it more adjustment. I fully loosened the nut but I couldn't get it to come out of the cavity. The nut seems too large to come out. I did a search and all the posts make it sound like it should come out easily. Do I need to drill out the cavity to give it more room? This is a Korean made Squier, but I'm not sure of its exact year. It does have a Fender 50th anniversary sticker on the back so that may put it at... 1996? I don't know if that makes a difference with the design of the truss rod nut cavity.
