I've used EMG pickups for some time, and it happened that I sometimes had to rotate the male part that's going in to clean the contacts on the jack. With this I don't think that I'll have that problem. It's drop in replacement for EMG solderless so that's' great, and I'll be getting more soon for my passive instruments (obviously mono versions). But to be honest, I'll wait until the monos that I have start to die before I get this. It's worth it if you're buying new, but if you already have something and it's working, I'd rather keep it until it fails and then replace (which can be years to come)
