You should check out Lundgren as well, pricey but he will customize them for your gear / ear. They sound close to 81s but better IMO, perfect for Metal. I am hoping to try some BK nailbombs in my JP sometime soon.
i'm an emg guy all the way...BUT i hate their passives. so when i bought a passive for my kramer baretta, i went with the l500xl. i got it cheap as hell on ebay and i think it's awesome...even tho i'm probably ALOT less picky than you. :mrgreen:
Actually I retract that. I remember you were going for something passive with EMG features but still natural. I had a Bareknuckle Nailbomb and that really fits the bill. Natural but still extremely tight yet organic, and it cleans up well too.
