I've been selling off a load of old vinyls I've had since the 80s/90s as I don't even have a record player any more. I sold a couple to someone on eBay who has now messaged to complain that the album (Pink Floyd, The Wall) "sounds distorted". I asked what she meant and she's said "We played it and all the loud baselines have distortion on them". She hasn't complained about the other record. I can't say I'm a vinyl officianado, but does this make sense? I would have thought vinyl is vinyl, if it's not scratched or dirty, those little ridges make the needle move and that's yer sound? Can a vinyl be "distorted", and just on basslines?! How could that be?
