Low output vs. High output

[NightWinder]

Kinda hard.....5 turns more is'nt their patent. They can suck it!!!!

I also sell double vintage Ivory Bobbins : )

Are you serious? DiMarzio has a patent on using different wire gauges on each coil of a pickup?

So i couldn't use 44 and 42 on the same pickup?

You can if you don't tell anyone!

Tone Zone
Have you ever heard a bridge pickup that made a guitar sound like a giant mosquito attack? If you've run into this problem, The Tone Zone® is the solution. The Tone Zone® is hot enough to qualify as a high-output pickup, but it has a wider dynamic range-hard picking will produce a lot of power, and softer picking will be much cleaner and quieter. It's got tremendous bass and low-mid response to reinforce the bottom end and make the overall sound bigger. The highest single notes have depth, and chords sound huge. Patented dual-resonance coils reproduce more overtones than you’d expect from such a fat-sounding pickup. It makes a great match with an Air Norton™, PAF Joe™ or PAF Pro®, and split-coil mode produces an excellent single-coil sound as well.

Well they say "substantially the same number of turns" ... "and the wires constituting the coils are of different gauges"

The key word here is "substantially"

substantially
adverb
1 to a great or significant extent
2 for the most part; essentially

So they give an example where one coil is wound with 5,400 turns of 42 gauge, while the other may be would with the same number of turns of 44. They then say the gauges and number of turns constituting the coils can be varied to emphasize certain frequencies.

They go on to say that using the exact same number of turns will result in less hum, but that can be changed to get a certain sound.

So as vague as it is, I think they have that covered. I doubt they would go after a small pickup maker though.

But yeah, change something and you are safe. I think EMG uses something like this in some pickups, but who would know? It's hard to tell what they are doing. They have no patents, but their "secrets" are locked in epoxy...

Change something, as in having one coil wound around a bobbin larger than the other? Fewer turns of a larger circumference in coil 1 vs coil 2 could provide effective noise cancellation and get around the language of the patent.

I was going to say that. Of course that requires a new bobbin...

[Dave Kerr]

Or just wrap a few layers of tape around one bobbin before winding. Or use a thin blade in one bobbin, thick slugs in the other. Or...

I was going to say that too! lol It was too much to type! I was supposed to be doing other things, and trying to get off the computer! Lots of good ideas bouncing around here lately.

I see we think alike anyway. Must be a Dave thing. How many Daves are here? I know Possum's a Dave too.

Sorry, I mistaked you. I was thinking of two wires on the same bobbin. I refer to them as "fusionWinding", which I do . Totally different. They can still SUK IT though....: )
