Any reason not to use this cable for 4-wire humbuckers?

[rjb]

Title sez it.

Mogami W2929; 28AWG 4-C with foil shield.
Here's Mogami's spec sheet:
MOGAMI® - Ultraflexible Miniature Cables

Markertek has it for 65 cents per foot.

Alternate question:
Does anyone know the manufacturer and part number of the 4-C cable sold by StewMac and Mojo?
I'm sure they don't make their own....
What about the "Lindy Fralin" wire sold by Angela? Is it Alpha 1122?

Thanks,

you want to have as drain wire for ground. 4 cond. + foil shield + drain wire.
that is, if you're doing humbuckers and you want to be able to access each coil individually.
if you just wanted to be able to split you could use one conductor for the output, one for the ground and one for the series link.
not a bad price, otherwise.


cheers,

4 conductor wire is about that price at mojo if you have an account
if you get at least 20 feet, it's 60cents a foot

That's a good point. Not sure how they are grounding the shield without a drain wire.

WD Music has nice 4-conductor cable. It's more flexible than the stuff at Mojo. It's .45 a foot if you have a dealer account.

I use either one of them, just depending on who I was ordering from that week.

I didn't know it was that cheap at WD, I've never ordered from there.
I'd love to set up a dealer account there, but I'm nowhere near big enough to have a stateID number..

I don't know why I typed "foil shield". Probably because I'd looked up too many different cables and had brain fever.
I doubt it could be "Ultraflexible" if it had a foil shield.
It appears to have a spiral copper wire shield- although I haven't found the type of shielding mentioned in words.
Here's a pic from Markertek's site:

PS: If you haven't checked the Mogami site, here's a blurb:
Most of these miniature cables were developed as custom cables for magnetic head leads for computer drives, which must be moved rapidly and precisely with very low force. All are very soft and highly flexible with excellent shielding.

I originally posted to ask if there was any electrical or mechanical reason not to use the Mogami cable- but I guess "you can get the tried-and true stuff for the same price" is a good enough reason not to buy it.

I'm probably wrong, but my understanding was that the bare copper wire was a ground wire only, not any form of shield and would only pickup as much interference as any of the other insulated wires in the pack. The foil shield would be the shield component which is grounded by contact with the bare copper ground wire in the pack that is soldered to the baseplate at the pickup end and a pot at the other end.

That's a good point. Not sure how they are grounding the shield without a drain wire.

It's a served shield (lots of parallel fine wires spiraling around the bundle of insulated conductors), not a foil shield (which would soon break from the flexing in magnetic-head service). The wires are tinned copper, so one just twists them into a stranded wire and solders that.

It sounds like very high quality wire to me. Model 2929-00 (4-conductor, 28 AWG) sounds like the right kind for pickups. The insulation is soft PVC, not teflon.

Mogami probably buys it somewhere, somewhere with a 2000-foot minimum (mentioned in the datasheet Mogami provides), and sells it in one-foot increments.

Not a big deal, but if you have a regular color code , black, white, red, green?
I see no green, and the Seymour duncan color code, and wiring diagrams most of us use, would have to be a bit different.
I currently use the mojo cable, I also like the 2 wire with shield.

I use a lot of the 2 conductor Mogami studio interconnect wire that was designed for Lavaliere mics etc. It's very nice, flexible OFC wire and it solders really well. It has a single ply of shield wrap and a conductive plastic jacket over that for flexibility and near 100% shield. I always assumed that Mogami made their own cable. The stuff you see on HBs is most likely made by Belden.

Oh, I thought it was a foil shield (as per the OP). The WD wire has a braided shield.

At Markertek I only saw it in 2000 foot rolls.

Mogami probably does make this cable

It appears that Mogami Japan does make this cable. See ftp://ftp.mogami-wire.co.jp/pub/mit/catalog-2000.pdf

Ah, and this would make yet another non standard color code for a pickup!

Exactly!
I pointed that out in post 9.
