I concur with what appears to be the majority of active EMG users being satisfied with how dead quiet their pups are. I own or have owned several different EMG configurations. 40J/40DC, 40DC set, JX set and a 45TWX set. Every time I perform the change to EMG, I wonder why I didn't do it sooner. Through many rehearsal spaces, gigs at questionable venues, and in all kinds of recording environments, I never get any hum. One of my basses that has the JX set installed has practically zero shielding of any kind and it was the only one that was installed by myself without the assistance of a local tech. I've been gigging these basses exclusively for the past 20 years. EMG has a customer for life with this guy. I'm looking forward to eventually having a PX/TWX combination in the future.
