I have owned this amp for years, and continue to play it daily. It has a warm clean sound. Great for jazz and blues. Very little info is available for these amps, however, I was able to find this bit of history about the company.
Sound amps were made in Mineola Long Island NY (1960's) by a John Dougherty, a former AMpeg employee, who later went on to run Marlboro amps, made by MICA (Musical Instrument Corporation of America), in Syosett. They were the original Peavey of their day, making transistor amps from single 6" practce amps, up to 2 X 12 combos. They used transformer driven transistor amps, which actually sounded tolerable.
The Sound amps were pretty well made, sometimes had no NFB, and used similar circuits to AMpeg and Oliver stuff (the DNA didn't fall far from their tree). Using 6EU7's and 7591s, 7868's and so forth.
John also invented and patented the Quadra-Sound Blender, an outboard effect, which combined tremelo, vibrato and reverb, to produce a couple of unique surf-like effects.
