Re: A2 vs A5 -I'm lookin for sound samples
What do you think about sound of my custom pickup?
https://soundcloud.com/karol-gotszlik/juicer-1m-500k-223-a5 (1meg volume, 500k tone 0.022uF)
https://soundcloud.com/karol-gotszlik/hunter-solo-kg (1meg volume, no tone)
I needed bright humbucker with not big bass and it will sound good in the mix. I like 80's glam metal era.
I think I succeeded, but do you think it's worth trying a2?
That's why I needed a comparison a2 to a5.
I like its sound with 1Meg Volume and 500k tone with 0.022uF cap, but I think it is slightly too bright/ringing(icepick) , so I thinking over 0.033uf cap
I won't ramble about A2 vs A5: it could generate hours of useless discussion, since all mags and coils are not created equal IME (I've here at least two sets of A2 HB's which seem clearer / brighter than some of my other HB's with A5... BUT they are not Duncan"s. If your pickup is a Duncan Custom and if you try a generic A2 in it, the sound will do what our fellow members say . EDIT: BTW, what about the Duncan tone charts and sound samples of Custom vs Custom 5 vs Custom Custom?).
BTW, in my understanding / on the basis of my own humble experience, A2 in the (Duncan 78) Van Halen PU's was most probably a way to compensate the thin bright tone due to a Floyd Rose in a Fender scale guitar without tone pot...
ANYWAY...
-I support the idea to swap mags in PU's until it sounds good... but it's not without possible downsides if you play with gain: loose parts left by multiple manipulations risk to make a pickup squeal.
-keep in mind that if the resistance of your pot sets the height of your resonant peak (= the relative volume of harmonics), the frequency of your resonant peak is set by parasitic capacitance. Most of this parasitic capacitance is not in the pickup itself but in external parts, especially in the guitar cable used. See pics 14 and 15 in this page:

So, if changing a cap on the tone pot is not what you want as Doc said, it
might be interesting (I repeat: "might") to shift the prominent high frequencies towards the mids thanks to a low value cap (somewhere between 120pF and 2200pF) between ground and hot - or to use simply a cable with more stray capacitance, like a longer guitar cord.
Seymour mentioned these facts in his old Q & A's but it disappeared (added capacitance being a solution "under the radar" and not necessarily easy to control since it requires specific measurement gear). It doesn't change parasitic capacitance in an indifferent parameter: it's a spec that I systematically tweak personally when I want to "tune" a passive pickup.
All that being said, the tone of your treble strings is a bit bright to me, the rhythm sound of your bass strings is pleasing to my ears and I like your playing. Good luck in your quest!
EVENING EDIT in order to share a few links…

[COMMENT - the important part is not about cables but about the effect of their stray capacitance on icepick frequencies and how to emulate this cable capacitance with cheap components...]

[COMMENT - an average 10’ cable measures 330pF to 450pF. So, when the guy goes from 75’ of cable to 0’ @ 6:50 and 8:50 in the vid above,
it’s as if he was disabling a cap measuring from 2475pF (2.4nF) to 3375pF (3.3nF), permanently connected between hot and ground.
This capacitive effect
can be handy when it comes to tame harsh frequencies, if it's properly dosed, with a rig whose character/gain doesn't hide too much the original guitar sound.]
And to conclude on a funny note, there’s the well known good old story told by Cesar Diaz about SRV and Radio Shack cables:
