Re: seth lover or 59'...HeLp me...
if you want a jazz tone in the neck, I'd go for either a seth lover neck, or an alnico 2 pro neck, and I think jimmy page used Alnico 5 humbuckers, but I'm not sure, so I'd use a 59' in the bridge.
seth lover neck, 59 bridge, or if you want uncovered
alnico 2 pro neck, 59 bridge.
I hope I'm not too late. Those will get you a nice combination good for any style of music, and the 59' bridge sounds phenominal clean, too.
For more distortion, you could use the custom 5, as Gearjoneser said. Any of the mentioned pickups will sound great. I would go for low output, because I find it more versatile. Good luck, and have fun with your wonderful sounding guitar.
