On the Anderson, each Ultrasonic PU has a 3 way switch, middle = off, down = series, up = parallel, then there's the "blower switch", basically the bridge PU in series (Mmmmm). The JPLP has a 59 PAF in neck (I'm led to believe) and a JP Burst (whatever that is) in the bridge which has a series/parallel switch on its tone pot (not my favourite PU BTW, but it's ok, the Ultrasonics in the Anderson are much better IMO).
Mmmm the JPLP, very nice guitar, though all said and done the Anderson is better (a bit like Mp1 to MP2 LoL). Although I had an alternative position on that tonight, Eve said she liked the sound of the JPLP more (had them both out to show off which led to the pic..).
They're both gorgeous guitars, I'm lucky to have them...
