An all original, rare find in perfect working and physical condition! Amp is on caster wheels and comes with a heavy vinyl, fitted slip cover. From my research, Fender apparently introduced solid state circuitry to their bass amps in 1981. It appears that this amp was produced in 1982, 1 year only, and all bass amps were discontinued in 1983. This is the only info I could find on the amp through the internet. I have to believe that it is true since I have never seen one before and there is very little info on it.
