The pickup height is very important with scatterwound pickups. I think people who say the Abraxas is thin have not set them right. The Abraxas is a beefed up Mule, so low end should be tad bigger, mids are a little more pronounced and the topend is more rounded. I heard great hardrock/metal clips with the Abraxas. It's not a metal pickup, but it can do a lot. I play classic rock/hard rock with Mules. It also depends on how tight the low end of your amp is.
You always can contact Ben at BKP for a recommendation.
