Before the large-scale production of a vinyl record, a scarce number of copies are pressed to test the quality and fine-tune any audio that may need to be adjusted. Once this process is approved, Mack Avenue makes an extremely limited quantity of these test pressings available to the general public. Packaged in a simple white jacket featuring a signature from the artist (when available), these collectible test pressings are available in extremely limited quantities.
