Re: pickup selection for alder body/maple neck?
You seem to be looking for a sound similar to what I seek for in an alder guitar and you seem to like some of the same guitar players I like so I can recommend you the same bridge pickup I use (Screamin' Demon) and in the neck I would choose something like a PAF Joe, PAF pro, SD '59. I have a clip I posted here some time ago for a Joe Satriani contest and there I use my main guitar (Super strat body type, Alder body, 3/4 maple top, 26 fret maple fretboard, Kahler Spyder tremolo, Screamin' Demon in the neck and a DiMarzio Chopper in the bridge) Although the Chopper it's not a full size humbucker, it compares a lot with the '59, but with a single coilish atack and more top end clarity...
Here's the clip and I hope I'm not too late to be of some help for you!! :fingersx:
