hi could anyone please provide the full wiring diagrams for the HH & MM90 configurations on the Axis Supersport....

many thanks, Tommy.
 
Seymour Duncan has a lot of wiring diagramms.. you can try this for example:
Wiring Diagram

It doesn't do exactly the same combinations as MM ASS stock wiring.. but it's a wiring diagramm at least.
 
The switching diagrams are available on the MM site.

If you want the actual wiring diagram, you'll have to email the customer service folks. They have the schematics handy.
 
thanks.

i have emailed customer services as the ones on the website are not detailed enough.

i am putting in a seymore duncan Phat cat P90 pickup in the neck of my humbucker ASS and am a little unsure as to do so at the moment if anyone has ever done so and has any tips? (Gotta do it myself and have replaced pickups before although this is not as straight forward as my strats in the past and cant afford to pay somone to do it! haha)

thanks, Tommy.
 
Will it physically fit in the cavity?

In terms of wiring, you'll have to think through how you want the split coil sounds to work in the 2 & 4 positions, or if you want to do something else there. 1 of those positions will end up being out of phase with the neck p'up (since it's a single coil). But with that switch you can wire up just about anything you'd like.

The Axis with P90s is a great combination. I have an original Sport with the MM90s, it just kills. Very jangly & twangy.
 
the Phat cat will fit the cavity thought it wil take a lot of adjustment to pickup it self but thanks god nothing for the guitar so this is a reversible mod
