Ok I ordered from ebay a Chinese rail pickup for my Japanese Squier telecaster. The sounds is really good for less then ten dollars. I have these in a strat parts caster now this problem is occurring in both of them ! So something is up and I need to hear from someone who is experienced with these. Everything worked in the Strat Neck and Middle then comes position 4 and 5 . Hum which shouldn't be there not normal hum it is relatively loud. Now I am not a slouch on wiring but this has me puzzed of course if you stand in front of the amp it gets louder and if you move away it goes away . Doesn't do it on the neck and middle . Well today I wired in the bridge pickup for the telecaster . I installed it no problem but the hum was horrible ! I corrected a few things wiring wise not related to the pickup I saw wrong.. and even added a ground wire and it quieted down enough that I could use the noise gate on my modeler to eliminate it completely but being as these are humbuckers why is there a hum period ?? and why only on the bridge pickup ? I know how to read wiring diagrams . and can correct things and diagnose as I go . But this has me puzzled never had something I couldn't figure out .
