Here is a valuable resource on the HotRod. http://studentweb.eku.edu/justin_holton/

There is a whole lot of discussion on the Fender forum as well just do a search over there on later Fender amps.

I used to have one and felt that is was a nice amp.

Mine had a plate on the back that said Made in the U.S.A. and I verified that by removing the rear panel.

If I remember correctly the jacks can be troublesome being mounted right to the circuit board. All this info in on the first site I mentioned.

I hope this helps.
