I've bought into most of their adpaks (1/2 price sales). My AD2 originally came with the Fairfax 1&2 bundles for free, then I bought up Studio Rock, Pop and Progressive. Later I bought the Black Oyster, Blue Oyster, Black Velvet and Retroplex (Vistalite).. oh, and I've got the Jazz Sticks and Jazz Brushes as well as the Funk paks.. I love em all.. but my go to's are usually Black Velvet for that snappy snare and the deep Arena sounds and Fairfax vol 1
