positions

Can anyone tell me what the 3 positions on the $$ switches correspond to? I think it may be parallel up, single middle and series down, but I'd like to be sure. Thanx, Pete

Hey Ollie, maybe you can answer a question for me: "on the thumb 5 string, why do they angle the neck pickup and have it so far back compared to the pickup layout on the 4 string? I assume it is to keep the B string tighter, but is there any particular reason for it?
