For the Neck position try a Mule - Supposed to be a hot version of a PAF
As I understand it, Mules are within the output range of original PAFs but towards the hotter end of that range (likewise, Stormy Mondays are towards the lower end of the PAF range). My understanding has been that there was a noticeable amount of variation in the "original PAFs", and different models of the "vintage" BKP humbuckers cover different parts of that range.
If, though, by "hot version of a PAF" we mean "similar tonal characteristics as a PAF, but noticeably more output", that would probably be an Abraxas.
