Update:


I just had one of the AS57 pickups (the bridge one) go faulty on me, it's gone open-circuit so that instead of reading about 6k it reads infinite ohms, not having a good run with these Entwistle pickups, I had some trouble with my Ibby guitar not sounding like it was supposed to, turns out the bridge Entwistle HDN pickup had been wired-up incorrectly at the factory where it was made, it had been wired up so that only one of the coils worked, the wires that were supposed to have gone to the other coil had been soldered together and the short wires coming out of the non-functional coil had been soldered together too, i have since fixed the bridge HDN pickup so it is working as a Humbucker rather than a single coil.


I'm not going to bother getting a replacement for the faulty AS57 pickup since I'm going to be swapping them out anyway.
