Tribute Fallout humbucker swap

Hi guys,
I'm an happy owner of a Tribute Fallout, I already modded the circuit about an year ago to best suit my "needs":

1. New alpha log pots (harder to move, no push/pull and a variable treble bleed)
2. "Bright" switch on P90 (high pass filter, I love to use it with overdrive, it really demuds the pu)
3. Series/parallel switch on the Humbucker (I don't like push/pull and I slightly prefer the parallel position than the single one)
4. Black pot covers (I simply prefer this colour on this guitar)

I'm pretty happy with the mods, they really work great and now I'm planning some others: first I want to swap the humbucker with a slightly brighter one, the problem is that I'm not a grat expert and I need your help. The tribute Fallout has got an G&L AW4470B humbucker in the bridge position, but I couldn't find many info on it:

1. http://guitarsbyleo.com/FORUM/viewtopic.php?p=37
2. http://guitarsbyleo.com/FORUM/viewtopic.php?f=13&t=13821

G&L Humbucker AW4470B = 17.05k ohms
G&L P-90 AP4285B = 7.53k ohms

As you can see the impedance are very umbalanced (in the middle switch position the P90 is more prominent) while volume-wise they sound quite balanced to me (no measurements).
I've also seen that older US models of the Fallout mounted the Seymour Duncan JB Model TB-4 humbucker https://www.seymourduncan.com/pickup/jb-trembucker.
Here's my problem: I would like to put a lower output humbucker (something like Gibson '57, SD Pearly Gates e.g. https://www.seymourduncan.com/pickup/pearly-gates-trembucker?__uuid_ref=5b0d2277d5048?__uuid_ref=5b0d2277d5088), but I fear that the volumes would get umbalanced.

What do you think about this operation? Will it work as intended? Have I got to look for another P90 to couple with the vintage Humbucker or it's better to simply drop the SD TB-4?
My final goal is to have classic sounding rock/blues guitar with just a couple of modern feats and good versatility.

Sorry for the long post!

bye,

Those are some cool mods you added! I can't speak for how the pickup swap will sound. My guess is that by putting a lower output PU like a 57 classic in the bridge, that there may be some volume imbalance between the stock neck and bridge pups. Also not sure how a P90 with an Alnico 5 mag will sound with a softer Alnico 2 humbucker. I guess just stick the humbucker in the bridge and then see how it sounds and go from there.

Sorry I don't have any experience to suggest what would pair well with the P90. As you noted, originally the USA Fallouts had a SD JB in the bridge position, later changes to a G&L designed alnico humbucker. Both are pretty hot. You may want to reach out to the pickup supplier for there suggestions. I know SD has an online tool to help narrow down the field. Once you have it whittled down to a few perhaps their customer service or tech service could provide some recommendations.

Remember that it is not useful to compare DC resistance between pickups of different types especially; DC resistance alone tells you nothing about how hot a pickup is.

Hi Danley,
I know that the resistance and volume relationship, that's exactly the reason I'm asking for advice here! I can't find any place on the net to check pickups volumes (only on the DiMarzio site).
I would also like to keep a similar impedance ratio between the pickups to preserve the balance of the sound of the pickups in parallel.

bye,
