Actually, it kind of is. Kind of. I think.Not a Gretsch amp. Not even close, for the specific reasons @wabash slim mentions.

In the "that much is true" corner: FGEnterprises of Addison, Illinois was also known as Fred Gretsch Enterprises. Definitely, fact.
In the "I think I read somewhere that...." corner: FGE was set up by Fred after the sale of Gretsch to Baldwin, in order to distribute items of musical kit to the stores that Fred already had relations with. A guy's gotta make a living. Definitely the company distributed Bandmaster harmonicas (made in Germany) and, clearly, amplifiers. Calling this a Gretsch amp is very much a stretch, though.
In the "wild supposition" corner: it could have been made by Valco, maybe, but to me it looks like a Japanese amp. I've seen very very similar amps branded "Zenta", which were made by Guyatone (hence the "GA" model number maybe, although it might just stand for Guitar Amplifier).
Who knows? Not me.

In the late seventies I had a cataloque from Conrad Elektrinik which was a distrubutor for electronic components for DIY hifi-builts and things like that.
Besides components and speakers there was a column especially for guitarists. I remember that there were several solid-state-amps that looked similar to that one. They were so cheap that even I-as a penny-less student- ignored them.
What is interesting is that there were tons of Shin-Ei-Companion products listed there for very, very little money.
I bought a Wah/Distortion model that I played for several years until I gave it away.
Recently I noticed that these pedals go for incredible sums on the collector`s market.
A guy's gotta earn some money. All he had at the time was a reputation and an address book.I find it hard to believe that Fred Gretsch would put his name on that.
