According to the guy at Unofficial fender Hot Rod page (http://studentweb.eku.edu/justin_holton/faq.html), he has this comment on 1996 Hot Rod Deluxe:

Also, the earliest Hot Rod Deluxes were made in 1996, and had a "50th Anniversary" logo on the back. Since this amp is arguable the most popular in the world, I'd hold on to the "50th" amps as they may become collectable.

My Blues Junior is 1996 (GE, aka May 1996), so i am wondering: should I mod it (Using BillM's mod, of course). I will definitely add the Bias mod.
