I feel that the neck Abraxas is basicaly a Mule with a touch extra turns, am I wrong?
not really
neck abraxas is wound just as hot as the mule, but I believe it has less asymmetrical coils, which would mean a touch more mids and less bass
the bridge pup is wound with a thinner gauge wire, so it's a different pup by nature
it's not the same of overwinding an 8k pup up to 14k (that would be physically impossible, actually)
an overwound mule set be more like a vhII set with alnico 4
that would be quite interesting
