The other day, I was fiddling around with the neck pickup height and pole height on my core model Starla, trying to get the neck to sound brighter, etc. I noticed with the coil tap engaged that the screw coil is the one that remains active. I noted with the screwdriver tip touching the pole screw. Usually, it’s the other way around, usually, the slug coil is the one that remains in the circuit when the tap is engaged. This seems very unusual – I've never seen this in 20+ years of playing. Has anyone else noticed this or seen this before? Or can anyone shed any light onto why this could or would be the case?
