Hi there. I just grapped a beautiful Fender Am Std Dimension Bass 5-string (HH-configuration). I looked into it, because I would like to split the coils similar to the American Elite HH version with the 5-way toggle switch. From each coils comes one wire plus one for the ground. So three in total. Currently the two hot wires are soldered to the corresponding Volume pot (it is VVT). Does anyone know whether this is series or parallel in its current configuration? Thanks!
