I have 2 1930's Gibson E150 6 string lap steels I purchased several years ago off eBay. Their Charlie Christian pickups have the warmest sound I've ever heard. Has anyone ever tried using a Charlie Christian pickup on a PSG? I would entertain having a professional do it using both pickups. I know its a weird request... but the tone may be worth it.

I've owned ES-150 guitars with Charlie Christian pickups, and I agree they sound great, but I see problems doing this:

1. They're 6-string pickups. You could narrow the string spacing or use two of them, but it's not going to really fit either way.

2. You destroy the value of two EH-150s, which are fairly valuable these days, not to mention fairly hard to find in good condition.

I can't imagine anybody doing this, but what might make some sense would be to find somebody to use the same materials/methods and wind you up a 10- or 12-string version. The magnet material is different than a modern pickup, and also the magnet wire is a different gauge. I believe Duncan used to make a Charlie Christian-style copy, perhaps they or someone else could do this for you. I just noticed also that Jason Lollar makes an 8-string steel "faux" CC pickup, here: http://www.lollarguitars.com/replacement_pickups.htm

I do agree, they're great sounding pickups, either on guitar or lap steel. Danny Gatton used to use one in the Tele rhythm position sometimes, I had a hard time not tearing up my last ES150 and doing this. But I held myself back.

He also makes the "real deal" ... I make the magnets for them ...

Heres an ES version ... smaller bar magnets

Here's the EH version ... larger bar magnets

Rick, are these the same style cobalt magnets in the original Gibson pickup?

36% cobalt steel is no longer commercially available in the amounts needed ...

I did find a place in China that would forge it ... but the catch was the minimum order was something like 100,000 TONS ...

I use a steel alloy that is hardened (heat treated) and then cryogenically treated ... for these and my steel horseshoe magnets.

I also make neodymium based CC magnets ... Heres a set of mounted in an EH150

In regular 6-string guitars with two of these C.C. pickups (rare, but I've seen 'em) what do they do, put a coil at each end of the bar magnets?

Duke Robillard worked with Jason on these "Real Deals" ... tweaking every little thing.

Duke used them ... along with his originals ... on the New Guitar Summit project he did with Jay Geils and Gerry Beaudoin.

Anyway ... the blade yolks "like" poles ...

This sets up a degaussing issue ... I've remagged several originals ... they needed it badly.

A second blade ... yolking the other end would work ... but it would further facilitate degaussing.

I messed around with magnetic orientation ... magnetizing them through the thickness (making one "face" North and the other "face" South ... instead of magnetizing thru the length (making one end North and the other South).

Through the thickness ... is the orientation I use on for my "NIB version".

So how do they normally put two of these in a guitar, one at the neck and one at the bridge?

The ES magnets are 3.5" long and 1/8" thick.

The EH magnets are 4.5625" long and 3/8" thick (they are super heavy).

I imagine that in a spanish guitar with two CCs ... each would have its own set of magnets ... ???

Right, but then which direction would the magnets point? Presumably, the neck pickup magnets would have to point towards the bridge pickup, almost to the point of contact....would that have an effect on the bridge pickup?

It would seem the bridge pickup magnets would have to extend under the bridge and tailpiece of the guitar, if possible. Sounds like a lot of problems.

Why could not a coil/blade be attached to each end of a single set of magnets? Since the poles would be opposite, the coils would have to be reverse-wound or reverse polarized to be in phase with each other when they're both on, right?.... but, seems like a single assembly of two pickups could be made. Of course the distance between the two pickups would vary for different guitars, requiring different length magnets for different models....but seems like that could be done.

What you are proposing sounds like a cool idea ...

Jason is always "into" doin' neat stuff like that ... he just has to find the time ... and someone needs to commission one.

I can make magnets that would accomodate any configuration and/or size ...

To get back to the initial post ... I have seen a 10 string EH 150 with a CC ...

I believe Chas Smith has one.

I don't know whats "under that hood" ... but I'd bet it is pretty cool.

My Gibson Grande Console has two seven string CC pickups. BUT,,,they have adjustable polepieces! Like a P-90. I've never seen any others like them. They do sound great. JB
