i have a screamin demon (seymor duncan) in my usa jackson, and that is one one hot pickup, i believe the pickups in my ibanez rg-570b are demarzios (vintage 7,a vintage single coil,and a vintage 8) although not as shreddy as the demon is the dimarzios have a unique quality to them. i like both realy but its like comparing elephants to monkeys it cant be done because they both do different things. i have yet to try bill lawrence but thought about having him make me some customs for my strat(mexican made) which i just put some texas specials in and love. god bless tim pate
