I have 2 early pressings and I enjoy them . The producer mentioned earlier did an outstanding job , especially considering the “ Era “. I wish I had an MFSL pressing , but not at current collector prices . I remember watching a documentary where they discussed the drum track for BOTW, being partially done in an elevator doorway in the middle of the night . Apparently the night watchman came off the elevator unaware and was quite startled . It’s too bad that the Classic Rock era suffered from the AM car radio mix . But it’s interesting to see people like Jimmy Page using a metal lipstick tube to enhance his slide work . And Pink Floyd’s homemade tape loops to add the sounds to some early music. While my system lacks any kind of tone control or digital correction , I find tube rolling alleviates some issues , YMMV. It is a crap shoot sometimes , but It is what it is ! Happy listening .
