Admittedly, I've only had these pickups installed for 3 rehearsals, but so far, so good. I'm playing with 2 guitarists, who love their low mids and overdrive, and am having no problem at all carving out a space in the mix using these pups. I've tried SJB-1s, QPs, Fender CS60s, and DiMarzzio Ultra Jazz. These get the nod. Nice stuff, Seymour!
