I was a diehard 59+JB guy for a long time. Then, when I got the Kraken (Victory's 5150 clone) the JB became just too mid-rangy for me. I EQ'd a ton to try and fix it, but wound up deciding to go another direction. Full Shred, Steve's Special (DiMarzio), Custom Custom, and finally Pegasus all got a try. I've stuck with the Pegasus now, and most of the tracks on the album were cut with that combo (59+Pegasus).
It was hard for me to tell much difference from Aaron's video, but in person, I can say that I really liked both the Steve's Special and the Full Shred, but both were lacking a bit in the bottom end. The Pegasus was the key there.
