A common and popular upgrade with these amps is a speaker swap. This PR has got an Eminence Rajun Cajun 10" ceramic speaker in lieu of what would've been a stock Utah or Oxford, and it sounds wonderful! More efficiency, tighter and fuller low end, and stronger trebles make for a more stage-worthy combo that can hang in a band mix.

The aforementioned Pull Boost volume pot was replaced with a standard volume pot, reverting it back to the more traditional style PR circuit. There's evidence of an old potentiometer or switch having been installed on the back of the chassis, but that's been plugged. The upper back panel was also replaced at some point. It has otherwise remained in great overall shape with light cosmetic wear.
