split coil flatwork dimension

[Stan H]

I wind mine at 10,000 turns per coil and get 5.03k (per coil).

Hmm Stan ..what wire are you using..?

Doing some Googling I found this at the Telecaster forum. Emphasis added:

P-Bass pickup winding advice needed
Hey, I need to make a magnetic pickup for my EUB and want to do a P-Bass style with alnico slugs because of the hum-cancelling design.

I want find out how much i should wind each halve, apparently they read 10Kohm so should i wind each to 5kohm before joining the regular coil to the reverse polarity reverse wound coil?

Or should each one be

10kohm

Hi, wind both the same, 5K this will give the best hum cancelling. But dont wind by Kohms, wind by turn count. This way both coils are wound with the exact same turns and will be or should be close to noiseless. About 4750 to 5000 turns each coil should put you close to 5K, check periodicaly through the winding process with an Ohm meter to see where you are at. Of course you know what to do when doing this if you are winding your own. Hope this helps.

244. What makes a bass pickup?
A bass pickup has similar components as guitar pickups but traditionally had 4 pole pieces as compared to 6 or more on traditional guitars. Now days I’ve seen 3 to 9 strings basses which create a need for modern design pickups. Early Fender single coil Precision Bass pickups had between 8 & 9,000 turns and the split coil Precision Bass had 10,000 turns per coil and wound in opposite directions for a humbucking effect. Jazz Bass pickups where wound under 10,000 turns because they had a longer winding length and if wound to hot the pickups would loose clarity and presence. Early Gibson bass pickups would be wound with 20,000 of 42 gauge plain enamel wire and would sound full but lacked presence. Rickenbacker bass pickups often used a .0047 mfd. capacitor in series with the output to give the pickup presence and less bottom. Fender Precision and Jazz bass pickups usually have two poles per string to keep the output balanced as the string vibrated from side to

I guess I'll just have to wind one and see!

[mick]

you will likely find that 10,000 turns = approx 5k , just wound one today @ 10,200 with PE and it came out at 5.4k , confirms the wind count on the 60's one I rewound...

Yep, Mick's on the money there. I wound a coil not long ago with similar results.

Mick

Sorry, I meant 10,000...just edited my post.

[David Schwab]

I guess it makes sense since it's such a short coil. But it seemed like a lot of wire initially. It's not like 10,000 turns on a Jazz bobbin.

[mkat]

...that's right, because the pbass bobbin will use less wire per turn. A turn is a turn, you have shorter and longer turns depending on the dimensions of a bobbin or pickup design. So, to state the obvious, resistance per turn on a pbass coil is less than that on a jbass coil.

[murof]

5kohm at 10000 turns (per coil) for me too.....

[Stan H]

I have to say it's nice to see a bass pickup thread...there's just so little info out there.
