Top.
Vinyl has an issue with playing.
It plays perfect, but there is a light tinge sound that is barely audible in the background it happens about every 10 seconds or so.
I m not sure if it is the pressing itself or if it is damaged.
Possibly an ultrasonic cleaning could fix it.
Does anyone knows of Og pressings having this problem? Some light scuffing on the vinyl, but it plays without skips and just light crackles.
Very rare album, holy grail masterpiece.
Sleeve is mint Vinyl is vg- Still a nice piece.
