magnet swap in Gibson ceramics

Hi,

I've got this 2006 Gibson Explorer with the stock ceramic pickups, and before I invest in Phat Cats or the like, I'd like to see what I can do with a magnet swap. I imagine these pickups are pretty hotly wound, so there may not be that much I can do with a magnet swap to get them sounding more classic-like. But for the low price of a magnet swap, I want to at least give it a try first.

To give you an idea of my preferences, here is what I think of some other humbuckers that I have:

'57 Classic and Classic Plus. I have these in my MIJ Epi SG. I like them in that guitar OK, but they don't cut it in a Paul. Too "chewy" and not enough treble. The neck pickup ends up practically useless in a Paul. Very smooth pickups over all, which is great at low gain, but doesn't cut it for me under natural amp distortion, let alone with any stomp boxes. I need an icier attack and more treble (or maybe just less bass). They get too muddy. They are really good for jazz and blues at low to moderate volumes, but not good at all for loud hard rock IMO.

Burstbucker V's in my 2004 LP Standard. Swiss cheese body. With enough tweaking, they are bright enough, but the adjustments are rather extreme (neck pickup dangling below the ring and practically falling off the adjustment screws). Even though I have the tone where I want it, they are still a little bit too smooth for me. I think that perhaps I like the magnets, but they are simply wound too hot for my liking. Or maybe it is the other way around.

Stock humbuckers in my '68 SG Standard. My favorites. Bright and wicked sounding. Very sharp attack. But they do mud up if they go loud enough, and they are very microphonic and feedback prone. The Burstbucker V's in the LP are better in those respects. They keep definition better when you play at full blast.

So, I am thinking that I need a magnet that is pretty weak to combat the aggressive winding of the Gibson ceramics, but one which also gives me a full EQ range, without dropping the treble or what have you. A2's in the '57's don't have enough treble IME. A5's in the BBV's have enough treble, but don't have a sharp enough attack (too smooth). Ceramics sound like the worst of all worlds to me. They are at once too thick and too brittle, and don't seem to have a lot of tonal sweetness. The one thing they have going for them is a good poppin' attack on the note. They are nice and sensitive to the right hand variations. But what good is that when they sound like **** tonally?

Then again, maybe my hearing is shot and I set everything up way more trebly than I should. :D

Also, I'd need to know what dimensions I need for the magnets. AddictionFX guy has various sizes.

Thanks for reading the manifesto. I hope you can help me out.
 
Re: magnet swap in Gibson ceramics

I have a 500T that I put an A8 in. The original mag was a double thick ceramic and it had small side mags. I pulled all of those out and put in regular-size plastic spacers so a standard alnico would fit. This basically made it a 498T with an A8. For more vintage tones, and less output, try an A2 or UOA5.
 
Re: magnet swap in Gibson ceramics

The 496R (your neck pickup) is a ~9K PAF type, I've heard of people swapping in an A5 and using it as a bridge pickup and liking it.
 
Re: magnet swap in Gibson ceramics

Are they potted? If not, maybe I could peel some windings off. 9K is a bit hot, considering that I even find my 8K Burstbucker V's a tad much.
 
Re: magnet swap in Gibson ceramics

Yeah, it's potted. Gibson pickups are easier to unwind though, because of the way they're taped, but you better be really careful doing that. If you haven't done it before I would not recommend trying it with a pickup you care about.

I would try it first, it's gonna be a bit different than a BB.
 
Re: magnet swap in Gibson ceramics

Blueman, A8? How do those compare to A5's and to the ceramics that are in the pickups (496R and 500T)?

What's the word on A3's and A4's?

KingIzzo,

Thanks for the words of warning. I trust myself to do it without screwing up the pickup, but the simple fact is that I 90 percent likely won't do that. If I try the swap and still don't like the pickups, I will just put them back to stock and sell them to help fund aftermarket pickups.

You're not into overwound PU's, and this seems like it would be an exercise in futility. They're both hot. You'd be much better off selling them and getting a pair of Seths.

Pretty much answers my questions. I just thought it might be worth a shot before chucking them and spending a bunch of money on new pickups.

I'm considering the Jazz as opposed to the Seth.
 
Re: magnet swap in Gibson ceramics

Well, I was making an order from Mojo today anyhow, so I threw in two Alnico V bar magnets just to try it out. The pickups actually don't sound too bad right now. Nice and snappy, which is good for my band. I adjusted them nice and low to clear up the high end a bit. But I would still like them to be less middy and more trebly if I had my druthers...and a little more "wet," if that makes any sense.

I also got black and white bobbins. I am going to saw the tops off those bobbins and try veneering them onto the tops of the pickups to make the black/white (not cream) zebras that I want. Also ordered gold polepiece screws, gold slugs, and gold open covers.

Also got gold pickup ring screws, height adjustment screws, pickguard screws, truss rod cover screws, jack, and knob pointers on the way. And some gold top hat 0-11 knobs. (:D)

Looks like I am going to have to have my jack plate plated gold along with another batch of hardware that I'll be taking to the plater. I cannot find anyone who carries a gold Explorer jack.

I'm also having trouble finding a gold Switchcraft right angle switch. Anyone have a link to someone who carries it? Gibson should make it for their '61 SG/LP Custom reissues, but I cannot seem to find it.

I'm also having trouble finding a clear shot of a '58 Explorer's jack plate. It may be that it was not gold after all, but like a LP.
 
Re: magnet swap in Gibson ceramics

My 496R measures 8.4K.

It sounds alright with an A8 as a bridge p'up.

It could go well with either an UOA5 490R or an UOA5 BB Pro R in the neck.

In the last six months I've received several Gibson p'ups and I've been trying to bond with'em, but it doesn't matter how much I try, I always come back to Duncans.

HTH,

+1. Yep, he'll be chasing his tail with hot PU's. He needs to go PAF or P-90 to get what he wants.

Well, they're actually almost deal-with-able as they are, so I'm going to try a swap for the hell of it before buying pickups. As you always say, it's a cheap and easy thing to try before dropping coin on a whole set of pickups. And I can just put the pickups back together and sell them if I don't like it.

If I do buy pickups, I think it is either gonna be a Jazz set or a Jazz neck witha Stag-Mag bridge.
 
Re: magnet swap in Gibson ceramics

OK, I just finished the swap in the 496R. Also put a gold open trim ring on it.

It was a complete success. The pickup was not horrible before, because I had set it up as well as I could. But it has so much more character and clarity now. It has a real voice, not that thick dryness it had before. A honk, growl, and a sneer, all without getting muddy. And, because I also put in 1 Meg pots and 103J caps all the way around, I get use out of the full sweep of my tone pots. 0 to 11 are all usable tones.

I may even keep the 500T stock, because an unexpected benefit of the swap was that I actually got a GREAT tone from the middle position on the switch. Man, it has some real character. Best in between tone I've ever heard. I normally avoid that position like the plague, but it's got some really cool stuff going on in this guitar. Kind of reminds me of Edward G. Robinson.

P.S. I also rewired it for master volume and a tone for each pickup. Way, way better than the stock 2V 1T IMO.

My 500T is in the 15K range as well. I pretty much enjoy it stock, so like you I decided (after a few beers and deranged thinking) I was going to mag swap it. I found some regular maple spacers and a rough cast A2 magnet laying around and made a HOT A2 pickup. I expected mud city and all, but I ended up with 90% the same sound honestly just with a little more 'give' and not as piercing and harsh. It cleans up with the volume a bit better and 'breaths'. Palm mutes are just as evil and tight, and it handles me tuning to C# standard for some Sabbath stuff with ease. It's my new favorite pickup. I took the neck pickup and put an A5 in it and it's in the bridge of my strat. Love that thing too. Gibson pickups have something to em I like... just need tweaked, well sometimes :)
 
Re: magnet swap in Gibson ceramics

In fact, if anyone looks me up on facebook, there is a short vid of us practicing one of our songs. We are in D standard and I'm using this very guitar. It's not very long, but sounds decent for an iphone recording.
 
Re: magnet swap in Gibson ceramics

Thanks for the info.

I have not dug into the 500T yet, but I do have an Alnico V magnet with the pickup's name on it. If I do decide to do the swap, is all I need two maple spacers like on the 496?

It seems the 500T must be a 50mm spacing, because 53mm bobbins are too large (but 49.2mm are too small).
