If the neck+middle position is noisy that sounds like a wiring issue. That position should be hum-canceling.
Noise from a single coil by itself is normal. I got tons of it before I changed the pickups in my only single coil guitar to noiseless ones.
Thanks
I'll check it out again later. I think the middle wasn't as noisy, but not silent like bridge.
I'll probably keep to bridge mostly anyways, but would still like an acceptable option.
