Interesting, will have to take a further look.
Just tried chucking Harvester of Sorrow off of Metallica's "And Justice for All" album through it to see if I could extract the bass from it...unsuccessfully. I knew it was probably too much to ask, but they really REALLY buried the bass on that album. You get little blips here and there of it coming through which is amazing in itself to be able to pick that out of obscurity, but nothing concrete enough to hear the full bassline sadly.
