I think the fly in the ointment is the obscure sized neck pick-up. I intend to use a lot of gain and saturation for a singing lead tone...and while playing I'm sure it won't be a big deal but otherwise as soon as you stop it's got that 60s cycle hum.
I browsed some DeArmound style pick-ups that would be a direct fit replacement but non specifically say they are noiseless or hum cancelling.
There is the mini humbucker option that would be a direct fit and I believe hum cancelling in all cases although there's not a lot of attractive options compared to noiseless single coil, humbuckers, and humbucker sized P90s. The PG13 from Dimarzio might do the trick but according to its specs it's a ceramic and I was ideally looking for a warmer Alnico 2, maybe Alnico 5 option.
Of course there's a chance I'll like the stock single coil enough to play the guitar and enjoy it for a while before I really want to get into changing something. I like everything else about it.
