    Default Who invented the humbucker?

    "I Feel I Was First With It": Ray Butts on the Creation of the Humbucker | Bacon's Archive
    by Tony Bacon

    TB: I believe Chet didn't like the original pickups on his signature Gretsch 6120.

    RB: No, he didn't like the DeArmond pickups that Gretsch were using at the time. It just didn't fit his style of playing at that time, mainly that thumb, finger style. He said they just didn't sound right. He said, "Why don't you make me a pickup?" Primarily what he wanted was a proper balance between the bass and the treble and the midrange, for that thumb effect he used, and he really didn't get it with those pickups. For one thing, the magnets on the DeArmonds were too strong. They kept sucking the strings and stopping the sustain. I saw some where he'd broken the bass-string magnets in two in a vice with a hammer [laughs]. So he said to me, "Why don't you make me a pickup?" I had done some experimenting with pickups before, so I said OK.

    My idea from the beginning was to build a humbucking pickup, because I knew about the concept from working with transformers. I'd fooled around with recording, and Ampex used the humbucking principle in the pickups of their tape-recorder heads, to avoid hum pick-up—they operate at a real low level, they're very sensitive to any hum. I was aware of the idea for years, probably from the '30s. It wasn't a new idea, been around practically all this century [speaking in 1995], and it's a very simple principle. You get electronics books, they'll explain it, how there's times when it's desirable.

    When you designed your humbucking pickup, what did you base that on? Where did the design come from?

    RB: Well, what I was thinking—when Chet told me why don't you build me a pickup, I thought, How can I make a pickup that's different? That's really what I was thinking about. How can I make something that's different, and maybe better, than what's already out there, than what's already been done? So I'd be thinking that over, mulling it over, and in the meantime I was working on my amplifier, and I was talking to a guy, Ralph Kenyon, who built the transformers for my amplifiers up in Marion, Illinois. I had conversations with him, told him what I had in mind, he said, "Yeah, that'd work." Like I say, I'd been aware for years and years of the humbucking principle, and so I thought if I can apply that to the pickup, there might be something new and better that people might like.

    Did you use parts from another pickup?

    RB: No, I just made it from scratch. The first one that I made and showed Chet, it didn't have screws—it just had metal pieces on top, like a single strip of metal, handmade, a magnet between them, and the coils I made out of pasteboard or something. I put it on a used Gibson ES-125 that I'd taken in on trade with somebody. It was low impedance, because I didn't have any way to wind coils, to wind thousands of turns, so I think I put about 200 turns on it. I got a little mic transformer in line, put it between the pickup and the guitar. I didn't have any tone controls on it at that time, just whipped it up to the guitar, and there it was. Chet liked it. I put it into the old DeArmond housing, because I didn't have any covers at that time, so they were there, they were made. The first ones I did with Chet I did like that, without the cover.

    Do those plates at the side make any tonal difference?

    RB: Oh, I don't know, it's kinda theoretical. If you made two and compared them you might not be able to tell the difference. Later they took the plates off in the middle. The theory was that there were eddy currents. Have you heard of that? If there's any kind of bulk metal brought into the magnetic field, the magnetism tends to cause currents to flow. Therefore, anything that's in a closed circuit would do that. I figured that this metal housing around these screws, if that was solid there, then there'd be an eddy current effect—it would be like a closed loop around the pole pieces. So I figured that if I broke it, put a gap in there, then they would cancel each other out. That was the thought. Whether it did or not, I don't know [laughs].

    Anyway, my idea was to use the humbucking principle and adapt it to making a pickup. You take a transformer, you cut a slot in it, and you got two poles. Otherwise it would be continuous—you cut a slot in it, then that separates the poles, and then the strings can have an effect on it, which otherwise they wouldn't have. Now you've got a pickup or a generator or whatever. I made a model, took it down to Chet, and he liked it. He said, "Sounds great," and he told Gretsch he'd like to use it on the guitars.

    Gretsch wanted to make the pickup themselves—they wanted the tooling. The basis for that, which I understand, was that they wanted to be sure of having supply. I hadn't done any manufacturing, I wasn't experienced at it. What they were afraid of was that they might need pickups and I wouldn't have them ready. I can understand their concerns. So I agreed to that. [Ray pops into another room and comes back with some pickups and other items.] When we first got to communicating about the pickups, what Mr. Gretsch wanted to do was to handmake working models, copies of my pickups, in the factory. This was to verify them, so that he knew everything was how it should be, that everything worked.

    This here was a bobbin that they made in the factory up there in Brooklyn, made out of vinyl, polystyrene, or something. They were proofs, because Gretsch was pretty careful about things like that. He didn't like to make mistakes. Here's one of the pole pieces, that's all my idea, some of the models I had sent. This particular one is a laminated pole piece, made of layers, and then there were some that were solid, also. They're not just for rockabilly. Take a closer look at the original humbucker and what makes it unique.

    Who did you deal with at Gretsch?

    RB: I dealt with Fred Gretsch Jr. They were in Brooklyn, New York, I think the third floor up in an old loft building there. Not too big, but they did a lot in there. They made drums, guitars, banjos, and everything else in that space.

    What happened when you went to see Gretsch for the first time?

    RB: Well, Chet had told them that he'd like to use my pickups in the guitars, so just over the telephone, I guess, we set up a meeting. I went to New York and went to Gretsch there, met Mr. Gretsch—Fred Gretsch Jr.—and we discussed it. 'Course, Jimmie Webster was in on the deal, too. We worked real closely with Jimmie. So we came to an agreement on a royalty basis. I furnished all the information and everything to make the pickups, and they went out and got tooling made. 'Course, they already had plating facilities—which they did with band instruments, all the other parts they made, metal parts of drums and so on—so they had everything to work with there.

    In the early beginnings, Gretsch said in their catalogue that they have these new pickups and how they searched countrywide to find the top engineers to design them [laughs]. I'm the one that did it! All that's just a big bunch of bull [laughs]. Anyway, that's what they put out at that time. They—I suppose they had their interest. They gave it the name. I didn't give it the name. They called it Filter'Tron, and they had a HiLo'Tron—all these names were theirs.

    Now, look, I have a ['60s] catalogue here, let me read it to you: "Introducing the new Gretsch Filter'Tron electronic guitar heads. Filter out hum, neon noise, crackles." Now here it is: "The finest engineers in the country were engaged in the development of the Filter'Tron and their main object was …" [laughs], yes, all those engineers—that was me!

    What happened, Ray, after you'd made the agreement with Gretsch for the Filter'Tron pickup?

    RB: We made the agreement, so we took it from there. I furnished all the drawings and information and models of the pickups, the parts, the bobbins, the case, all of that, and from that they had tooling made. I had already contacted a molder to mold the bobbins, and they used that same one. I contacted a source for magnets: The first magnets came from Arnold Engineering, they were up north. Then I was to serve as a consultant. That was part of the deal. Not just on the pickups, but anything about the guitars. When they first started putting the pickups on the guitars, one of the first things they had a little bit of a problem with was acoustic feedback, from the guitar to an amplifier, if you got too close. I figured out what was causing that, and I made a suggestion.

    I said in an electric guitar, you don't really need the same things that you do in an acoustic guitar, it's a different situation. I said the way to stop the feedback and probably get better sustain and better performance is to run the neck all the way through the guitar, and fasten the top to the neck, and do away with all that vibrating. See, the feedback was coming from that top vibrating with the pickups on it, mounted to the top. When you put on that neck solid, straight through, and fasten the top to it, it's locked in and it can't vibrate. So that solved that problem. And then later, Chet came up with a design for a guitar which was basically a semi-solid guitar, and it had the artificial f-holes—that was one of the first ones he made that had the artificial f-holes. I was out at his house when he was working on that. I know we went and got some superglue when he was putting those f-holes on there [laughs]—he glued those f-holes on top of the guitar.

    [Ray takes a pickup from the pile of items he brought in.] Along the way I made this stereo pickup for the White Falcon—I designed that. That was Jimmie Webster's idea, he asked me to do it.

    How did that work?

    RB: Oh, it was basically quite simple. Just take my humbucking pickup and split the windings. Normally, you have one winding that covers all six strings, and if you just cut it half in two, you have two separate sets of windings: You have three strings that are independent of the other three. You just bring these out separately with their separate controls, and plug them into separate amplifiers, so when you pick the first three strings, it comes out this amp, and the last three strings come out that amp

    I've seen some Gretsch stereo guitars where you have two sets of three pole pieces on one pickup and the other two sets of three on the second pickup. So there are several versions.

    RB: The first ones that I made for them, you couldn't really tell by looking at it, it looked the same because the separation was done internally. So just looking on the top of the pickup you really couldn't tell. [Ray goes out again and comes back with a gutted Gretsch Silver Jet testbed guitar to show me, with wires hanging out of it and a large board attached to the lower half with more wires and switches.]

    That's interesting, Ray. What was that for?

    RB: Well, there's nothing special about that, I just told Gretsch I needed something I could experiment with, and they sent me that. It's an unfinished model. It was just for general experimentation. I used it for working on the Gretsch stereo guitars and for other purposes, too. I experimented with different control arrangements on that panel on it there—I changed that around—the panel made it convenient to work with.

    When did your relationship with Gretsch end?

    RB: Our relationship officially ended in 1975. That was after Baldwin owned the company. I was sent a letter informing me that they would no longer pay a royalty after such and such a date in 1975.

    What reason did they give?

    RB: Well, my patent application had expired. But that's not really the way it was supposed to happen. See, Mr. Gretsch and I had a handshake agreement, and to convince me that it would be OK, he had volunteered several pieces of information. He told me that they had done business with K. Zildjian in Turkey, the cymbal manufacturers, for over 50 years with no written agreement, and the same with Couesnon band instruments that they sold, made in France. He had been doing business with them for years and had no written agreement. He told me they were as good as their word. Which is fine, as long as he's alive, but when you die, well [laughs], you know, all that ends, and that's what happened. So it worked out fine as long as Mr. Gretsch was alive [Fred Gretsch Jr. died in 1980]. When they sold the company to Baldwin [in 1967], I kind of fell out the picture. In the meantime, they had moved to Booneville, Arkansas [in 1970]. When they moved to Booneville, well—they probably lost a lot of their key employees in one go. That can ruin a company. You lose your key employees, you're in bad shape.

    At the time Mr. Gretsch was alive, his secretary took care of all my royalties and everything. So when the company was sold, Baldwin just sort of forgot about everything. I finally got after them and they sent me a little money. Actually, Duke Kramer sent me a letter—he was still connected with Gretsch—and he said they felt it no longer applied, or whatever. But Mr. Gretsch had implied that our agreement would actually not have any end date. But that's all right, I never did feel too bad about it.

    I've also heard that it was Seth Lover who invented the humbucker?
