Not only does Dimarzio make some kick-butt pickups but they've got an amazing exchange policy! I bought some Area J's from an online Dimarzio retailer, and discovered that they didn't give me the sound I was looking for. I noticed that the plastic box they came in had a sticker that mentioned an exchage policy - as long as I send them in within 30 days I could exchange them for a different set of the same value. I contacted Dimarzio, got a return #, sent them in and they sent me a brand new set of Ultra Jazz pups (they paid the shipping). What other company can touch that?
