Yes it is. Old vibros are great little amps. Just don't expect to get the br00talz out of it obviously but for what it is, it's a nice deal.
I wondered why the frisbee was getting bigger, then it hit me.
if its pre cvs i think its a good deal.. i remember my step dad telling me that amps and guitars made by fender before it was sold to CVS are worth alot more
If your looking for orgasmic clean and light distorted tones then go buy it NOW!

Anything more and I would recommend something else.
