The 20W Octane will probably be the next thing I'll work on but it'll take a while...
The ESP has a really specific sound in itself, so I'm not sure how much the Super Distortion has to do with it.
The Antiquity is really nice for low/mid gain sounds. I might have to get another one for the neck position in my Les Paul as well because I find the Slash pickup that's in there a bit muddy.
From what I’ve heard clips of,the Seth Lover neck pickup sounds like it’s a bit leaner on the bass than others, so that might be a good alternative to look into if you’re looking to stick with Duncan’s.
