Hi, I have two guitars on the drawing-board that are both H-H. I wanted to use the P-Megaswitch that gives you the PRS combos but Stewmac say I have to flip the magnet in one for it to work. This is OK for the PAF style bucker but the other guitar will have Powerrails. I believe these have 3 ceramic magnets inside which is starting to deter me.
I thought I would be able to rotate the bridge pickup 180 and then wire it so the combos are slug+screw instead of screw+screw and slug+slug. I thought that would still give me the hum cancelling combos but Stewmac told me "no".
Anyone else got an idea?:confused:

Get a yahama 5 way .You can set it up any way you want.Theres 4 ways to wire a HB so the coils are in phase w each other so if its 4 wire no mag flip is needed.

You are on the mark about rotating one of the pickups to get noise-canceling "inside" and "outside" pairs.
I don't see anything on the stewmac drawing and text (http://www.stewmac.com/shop/Electronics,_pickups/Components:_Switches_and_knobs/Megaswitches/Megaswitch_P-Model.html?tab=Instructions#details)about flipping a magnet, BUT, if you simply rotate one humbucker of your matched pair 180 degrees - so that both slug coils are either closest to the bridge or closest to the neck - it gives you the one condition they do make clear: the outside coils must be opposite (magnetic) polarity. However, a bit more info is needed to assure that the inside pair combos on the switch are actually the inside pair at the pups. The stewmac drawing doesn't show polepiece detail.
I do not know the lug assignments for a Mega-P switch, and they don't show that info, either, so, I can't comment further on their drawing - too much think-ology required to interpret the Mega-P connections. But...
Take a look at this drawing from **********************: (http://www.**********************)
They used a Superswitch - one of my favorite toys. IF you re-orient (rotate) the neck pup as shown here (so that the screw coil is closest to the bridge, matching the bridge pup) their scheme gives you just what you have asked for - PRS combos, and all noise-canceling pairs.
I'd prefer to have the pups oriented the other way - slug coils closer to the bridge - for a couple of reasons. It should just take a little tweak to this GE drawing get that happening.
FWIW, I drew up the PRS combos on a Superswitch many years ago, but not with noise-canceling pairs (the pups stayed in traditional orientation, with slug coils inside and screws outside).

Ah yes, here's my version in Seymour Duncan color code, with noise-canceling pairs, and screw coils AWAY from the bridge assembly:

Thankyou, Deaf Eddie.
I sent you another email before I spotted your post here.
I will be having screws toward neck. I'll also try your setup with Bridge lowered but poles raised and then opposite at Neck. I'm using Alnico2 at Bridge and Alnico5 at neck... hopefully a nice mix.
Thanks again, Guru...The fog is gone and I now have clarity.
