Splitting the humbucker get my guitar a singlecoil-ish sound. Not only a lowering af the signal; not unless that somehow turns the tone into a singlecoil-ish tone, that the humbucker cannot produce. But no….it doesn’t sound 100% like a real humbucker. But close enough for me.
On my Anderson they do something with the humbuckers that makes them sound identical to great single coils. I think the split changes the components in some way. They are slightly lower output, so I have profiles dedicated to either HB or SC.
