warm, middy humbuckers for a semi-hollow

[Clint 55]

Sorry for dragging this thread out. But A2P neck and CC bridge will really be the only combo that will be 'warm.' Any of the other pups are kind of spiky with more or less combos of warmth vs spike and color. All are (or seem) nice tho.

Anyway, what I'm saying is it sounds like the cheapest/easiest way to change up the sound. Where do you guys like to buy magnets?

Mag swapping is always interesting and might please you BUT... without discarding in any way what others said, I'll insist on my statement in the answer 16: I "think' that AlNiCo mags in the stock PU's of an Ibz AS73 might make them a bit too bassy.

My reasons to tell this are extremely simple:

1)I've upgraded an AS73 by changing its PU's and bridge. I've also compared it directly to a handful of other semi-hollow guitars at disposal in the shop (Epi Dot, Hagstrom Viking, ES339... non limitative list).
Its material, shape and structure make the AS73 naturally bassier than other semi-hollow's. It needs "tight" PU's IMHO and IME.

2)I've still the stock pickups on the shelf here: for the fun, I've changed the baseplate of the neck PU and... stuffed both PU's with AlNiCo mags (polished A5 in this case).
With an A5 mag, the neck AS73 PU makes a passable bridge PAF clone but it's rounder sounding than other PAF clones because of its coils and magnetic alloys. I'd avoid to put it back in the neck slot of an AS73 because of this roundness...

Generally speaking, AlNiCo mags instead of ceramic (ferrite) increase the inductance and weaken the magnetic field, making pickups warmer and softer sounding. The stock AS73 hb's have been voiced for ceramic and are already soft souding as such. EDIT - And the stock covers make it worse: they are not "magnetically transparent" AT ALL. So, a first way to improve the stock pickups without changing their mags would be to ditch their original covers.

Now, maybe you'll be pleased with AlNiCo mags in them. Every guitar is different. Everey player too. Only you can tell. At least you know my own experience with some stock AS73 PU's.

The warm and middy tone while still cutting tone does not come from pickup or a tone pot.
IMO it comes with nylon or string saver saddles. I use a resomax bridge from Tusq.

Thank you for sharing your experience, it's very insightful! My impression of the AS73 is the same as yours: even acoustically it is a bass-heavy instrument. I guess with that in mind, you're right--I should be looking at pickups with a tight bass and a focus on the upper midrange and treble. Maybe a '59 Custom Hybrid bridge and a Full Shred neck?

Did you find the bass response was improved by changing the bridge hardware, like hamerfan suggests? I'll dig out the soldering iron this weekend and pop the covers off, see if that helps too.

*Just to be precise, I think the pickups are Classic Elites instead of ACHs, since it was made in 2015. The listed DCR (9.5k neck/11k bridge) is a little different from your measurements of the ACH, but it's still a darkly voiced pickup. For all I know Classic Elites are just a relabeled ACH, but there isn't much info to go on.

Albeit I didn't use the same parts than Hamerfan, I've found the acoustic resonance clearer and harmonically richer after an upgrade from the stock bridge to a Gotoh one...
Now, it was not only a question of materials in my case: the original saddles were not cut with care and it affected how strings were vibrating.
But nylon saddles are something to try, for sure.

Ah, OK, thx for the info. Yep, different specs. Not sure covers are better on more recent pickups, though. Let us know if pulling them off changes the sound...:-D

If you are concerned about too much bass in your guitar, I still recommend the A2P bridge for the neck. If it sounds too soft/loose/bassy, put in an A5 magnet. That makes it a Jazz bridge pup (Jazz and A2P have the same wind, just different magnets). The Jazz bridge with A5 is my favorite neck position pup in just about every guitar that I own (over 50 of them).

The stock 59/Custom has an A5 magnet which gives it a mid scoop effect. It has strong bright highs and articulate bass. If you need it to sound warmer and fuller you can put in a UOA5, A2, or (my favorite in this pup) A8. The A8 gives it a warmer feel, more mids, slightly softer highs, and strong but not overbearing bass, and a bit more output which works great in the bridge position. This pup with A8 is amazing in the bridge and splits to the Custom coil magnificently.

Very cool, thanks Doc!

I was watching the Keith Merrow pickup comparison video (I wish I had this resource 15 years ago when I was in a metal band!) to compare the 59/Custom with the Full Shred. Surprisingly, the 59/Custom gave me the impression of having a greater emphasis on treble and upper midrange (over 2kHz). The middy-midrange (somewhere between 300-600Hz) focus of the Full Shred was very nice too, as was its slightly tighter bass. I feel like I could make either work in the bridge position with some EQ futzing, though I lean towards the Hybrid for the upper harmonic sparkle.

Interesting stuff, much to consider...
