Anyone tried A3 in Burstbucker or Classic 57

I'm back to experimenting with my R7, which might one day have permanent pickups installed - haha! :rolleyes: I'm hoping some of you can save my soldering iron some wear and tear.

A Jazz N in the neck position is perfect. The bridge has been a never-ending quest, with virtually all of the 50+ pup/mag combos I've tried (not exaggerating there) having extreme and obnoxious nasal, congested upper-mids.

Finally turned to A3 mags, usually not a good fit for a bridge pup. But a C3 has now given me hope: sweet attack, almost no upper-mid nastiness. Two problems: first, output is too low to match the neck, and fooling with the neck's height greatly reduces its woody PAF goodness. Second, the C3 has little low-end punch. I would like a bit more punch but don't need all that much.

I'm now pondering an A3 in the following pups:

Burstbucker 3 @ 9.35K DC
Classic '57 @ 9.08K DC
For reference, my Custom is exactly 14.1K DC.

With stock A2 mags, each of these Gibbys was plenty loud and fat but had that snorting upper-mid thing. With other mags these Gibbys (as with almost every pup I've tried) came out as follows:

A5 - kept upper-mid demon, added harsl highs.
A8 - hard, sledgehammer attack and still the upper-mid thing.
A4 - decent, cut the objectionable upper-mid components by half, but with a sterile-sounding "thud" on the attack
A2 - Fat and warm but the upper-mid bump is really noticeable.

So A3 seems to be the only ticket here, and a slightly louder & fatter C3 is the grail. Any idea how the output of my heavily-wound BB3 and 57 will compare to the C3? And how about the lows compared to the C3? I'll likely do the experiment regardless, but I'm curious about your opinions on this.

not sure man, its worth a try in the bb3. its got a fat wind but ive never mag swapped one of them.

have you tried a custom/paf hybrid with a2 or degaussed a5?

I've got a 490T with an A3 in the neck position on a tele, which would be similar, but I haven't fooled around enough with it yet to say anything more than it sounds good with a practice amp... in the neck.

Maybe the problem is your amp or EQ, I think a lot of those combos you mentioned are well regarded by a lot of users. I would think a Custom5 would be exactly what your looking for if you need more bottom/output from a Custom3, I dunno. If the C3 isn't powerful enough neither one of those pickups with an A3 will be either.

I think A3's are an excellent substitute when an A2 neck HB or P-90 is too dark. Output stays the same but you get more treble & definition. Other options with more treble than an A2 are A4 and A5.

Likewise in the bridge slot, an A8 can 'shore up' an A2, by giving more output, treble, and a tighter low end.

The downside is that none of these other magnets have the character and response of an A2. You have to decide what your prioritiies are tone-wise and choose your magnet accordingly.

With A2's, it's kind of like a tube amp vs solid state. Tube amps are expensive, heavy, and full of downsides, but they have a tone and feel that nothing else does. Mind you, I won't be converting all my guitars to A2's, but they now have a place in my harem.

I've always been an A2 guy. I randomly acquired a JN and tried it in this guitar and now it's my favorite neck pup. So I grabbed a Jazz bridge thinking it would be a perfect match. It sounds like bacon in a frying pan.

The Jazz N has unbelievably high output despite measuring 7.03K DC (vs. the JN spec of 7.72K). I posted about this before and also contacted Duncan. Given the low resistance and blazing output, they suggested that the magnet might be heavily charged compared to their typical A5's. I don't have a gauss meter so I can't check that.

As for the bridge, the only thing that's come close in volume without nasty frequency bumps is the C3. It's best described as brown sound with smoother, sweeter highs. DC and C5 had harsh highs (for my taste), C4 was cold & sterile, C2 was very nice but a bit too dark. I rarely even try an A3, but I went for it on this C3 and it did the trick.

So the JN and C3, tone-wise, are absolute keepers if I can just get their outputs balanced without messing with pickups heights. Given what Duncan told me I will try a few different A5's in the Jazz and some A3's in the C3, see if I can even them up that way. If not, I'll watch that YouTube vid where the guy shows how to put a max charge into a mag. Then I'll pump up a C3 and see and see what that does!

And I'm sure I'll try the BB3/A3 and '57/A3, just because ...

Love to hear about your mag experiemnts. Keep up the good work, and keep us posted. We need more guys like you.

I can't find the YouTube link! I got it in the SD Forum a week ago but can't find it in my YouTube history or anywhere else. Meanwhile I've found these alternate sources:

From StewMac catalog, here's a poor man's magnet charging rig:
