There's nothing actually wrong with the stock switches, they just have big ugly ass screws to hold them on is all. I can't see them failing, they are pretty well built.
Of course if you change the 4 switches for switchcraft,which have counter sunk screws, you should change the chrome as well as it accommodates counter sunk screws better than the Jap chrome because its made for countersunk screws. Countersunk screws will work with the stock chrome though. And if you change the chrome you will need to change the roller pot bracket to AVRI as well.
I would change the pots the 500K Audio if you are wanting Quarter Pounders as 1Meg is pretty bright on a high output pickup. Alpha pots are just as good as CTS and almost a 5th of the price. you can get them at http://www.smallbearelec.com/StoreFront.bok
You'd want 24mm single gang Audio pots, then choose the value in the drop down menu. (500k)
And If you change the pots to solid shaft pots you'll need to change the knobs, the above website has them too, the large MXR ones are identical to AVRI Jaguar knobs except they have a flat head set screw whereas AVRI have a hex key set screw.
Once you start modding CIJ's you never stop because there's so much cheap looking crap on them you just want to replace it all. In the end it would have been cheaper to buy a second hand AVRI but I understand people don't always have ALL of the money in the one hit.
I have a CIJ Jaguar, the only thing CIJ is the wood, everything else has been replaced with American parts. I could have just bought an AVRI secondhand but it just didn't turn out that way. Plus I like poly necks anyways.
If you have any specific other questions just PM me and I'll help you out, I've come to know a #### load about Jaguars, Jazzmasters, Jagstangs, DUosonics and Mustangs over the years.
