The salesman in the music store which I shopped most often called those Gibson Recorder. He said it was designed for studio work. I remember they were pricey and a little ugly. As I recall they also weighed a ton.
This guitar had a few things Les Paul preferred
- low impedance pickups ( still humbuckers)
- a flat vs. curved top
- some on board effects, and maybe out of phase switch
My first electric was a 1976 Les Pauls Signature ( not a big seller, cheap!) that had similar electronics, that wide 'harmonica' Nashville bridge; but the body construction was semi-hollow, like a weird 335.
Miss it! ( stolen 1980)
The Marauder had a brief run, thanks to KISS.
That was actually my first "real" guitar (not because of KISS) - blonde with a white pickguard. Nostalgic me started looking around for one a few years back, and holey schnikeys, people were (and still are) asking quite the chunk of change for them. As in, $1500 and up.
