My 65 Jazz bass has an out put jack that is about as simple as it gets. If it stops working it readjust it and away we go. It's sooms that most of my newer basses have a monstrosity that's about 2 in long and unaccessable. So I have an hand made guitar with a chop stick wedged into the jack so it works. I am not feeling this. I am in the process of repairing my Cirrus. It's taken an hour and I'm just to the point of being able to order the 10 dollar part. The Knobs must come off, the preamp must come out and then I had to find a way of getting the jack out. None of this happens on the Jazz Bass. Now the reason for this post is why use these new jack since it's been my experience they don't work and are a pain in the neck to repair? I've not seen one of these jacks that functions as it should. Every one I checked has a dead spot as you rotate it. After a while you don't need to rotate it. Is there a trick to repair these thing without replacing them? Is their lack of function related to age and wear, although I've seen new ones do it? I have ordered a Switch Craft in the hopes that they are still a quality product.
