Sabian's SR2 line of cymbals are uniquely marketed as a "treasure hunt". These cymbals have come back to the Sabian factory after leading short lives being played by endorsed artists, being displayed at trade shows, or being restocked for any number of reasons. The bottom line is that these cymbals have been used, but very lightly - no damage was inflicted to the instrument. Cymbals from the AA, AAX, HH, HHX, and Vault series are all brought to the same place, where they become SR2 cymbals.
Back at the factory the original logos are removed, the cymbal is re-lathed, a secret step is taken (cymbal companies are notoriously hush-hush about their manufacturing processes), and then the SR2 stamp is placed on the newly-born instrument. The only marked differences are diameter and weight (thin, medium, heavy), leaving you to guess what the cymbal was originally. So why buy a cymbal with a mysterious past? The pricetag. These cymbals are sold at drastically reduced prices for what are essentially new products, allowing percussionists the opportunity to own what may have been an Artisan Vault cymbal at a fraction of the cost. You've only got to ask yourself one question: "Do I feel lucky?"
