Re: Flat out: Does the Phat Cat sound Like a Gibson P-90?
P90 magnets oppose. That means generally over time, there is some natural "Dun-Aging" to one of the two magnets anyway. I imagine if you went with an A5 and A2 combo, your A2 would be losing by far. That could cause it to become far more demagnetized over time, and you'd have more of a single magnet, non-focused pickup sound, which is not really P90 anymore.
In working with P90's & Phat Cat style pickups a lot recently, I've come to the conclusion that you may want to "Dun-Age" one of the two A5's in order to encourage a dominant/recessive relationship between the two magnets. But using two different magnet types isn't going to yield long-term success. IMO it doesn't even give you long term consistency, since you clearly have a stronger magnet attempting to re-magnetize the weaker one. You're just asking for one to re-polarize the other. After all, we re-magnetize and re-polarize Alnicos with stronger magnets, and they are more subject to demagnetization and re-polarization than a Ceramic for example.
In Zhang's illustration of the A3+A2, 2 and 3 have a closer relationship than between the A2 and A5, so I imagine that's why it worked okay for him, but still wasn't as desirable as the two A2's. If anyone wants to mod the Phat Cat I'd suggest two equally charged Alnico 5's.
