My opinion is that they are a very versitle pickup. It has soft highs solid mids, and what I consider a soft bottom. It's not a bright as a 59 and doesn't have the thump of the 59. I have a Vitural PAF and Vitural Hot in my American made Wolfgang Special and they absolutley rock in that guitar. It gives the Wolfie Special that early VH vibe. I like them an awful lot.
