EMC made some interesting gear during the 70’s… and had something truly amazing, a lifetime guarantee! Of course being they went out of business prior to 1983 the lifetime part ended up being pretty short.
The S300 Guitar Amp had the following specs:
EMC was located at
21819 Royalton Rd
Per google maps, the current building at that address is huge. Either they were really that big, or they just rented a portion of said building.
Beyond the S300, they also had a G200 and a line of PA systems.
In my first band, we had a EMC Gemini PA system, it was a 6 channel unit, and it had to 2 columns with 4 eight inch speakers in each one. It sounded ok, but when we paired it up with some homemade clones of a Peavey SP3, it could really rock.
Granted, such a unit was of no comparison to the next group I was in where we had 4000Watts triamped, and 4 speaker columns reaching nearly 15 feet high… yet, for the average bar or small club, the Gemini did a super great job.
