All SABIAN sets are “Sonically Matched” by our Product Specialists in the SABIAN Vault.  Rather than just take each cymbal off the shelf and put in a box, they are first tested individually and then for overall compatibility with the other cymbals in the set.  This ensures you get a ready to go set up, straight out of the box.  The AAX Promotional set consists of 14″ AAX Medium Hats, 16″ AAX Thin Crash, 21″ AAX Medium Ride and a FREE 18″ AAX Thin Crash
