I once bought a cheap guitar just because I had a little extra cash in my pocket and it looked pretty. I fully intended it to be decoration on the wall.
It was a Les Paul style guitar, dark burgundy mahogany body, translucent, nothing fancy... P90 pickups and black plate.
It was made by an unknown to me at the time brand. SX.
It arrived, and apart from needing attention to the nut and a couple of frets, it was pretty damn good. Set neck, which I did not expect, and reasonably well made with a handful of very minor cosmetic details, understandable at the price.
It became my #1 guitar. I was at a guitar bash style thing once with it, in 2003 or 2004, and there was a guy with a Gibson Les paul Jr with a couple of P90 pickups... and most preferred my guitar in feel and sound.
Sometimes (not often, I admit), you get lucky. SX make budget instruments but they do make functional instruments.
Other companies, not so much.
Anyway, some people like to collect instruments because they look nice. Why not?
