I own a Carvin DC400, but I swapped out the Carvin pickups a while ago. (I now have dual Tone Zones in it.) However, if I were to order another Carvin, I'd go with the C22J and C22B pickups. I like a big fat neck pickup for leads, and the C22J is their best for that. The C22B is their best bridge pickup, in my opinion. It is harmonically rich, has a lot of output, and stays full on the high notes. It can do classic rock to metal well. Their M22SD pickup has tons of output, but has a harsh high end and is, in my opinion, good only for metal riffing on low notes.
