Re: 4002 pickup guts
OK, potentially stupid question.
What about the bass pup? Same side by side wound pups, correct?? How about sensitivity?? Is the bass pup less sensitive?? There seems to be a pretty substantial dead spot in the center of the 4002 pup. Not really an issue unless your pup is not centered directly under your strings, which seems to be the case on my 77 4002. The bass pup on that bass has a huge dead spot under the A. So much so that when I tap the top pf the pup, directly where the A string passes over, there is no sound.
My A string does not have the output of the other strings and my pups are off center at least 3/32's, toward the E string. The treble pup is not to bad on the A string but the bass pup, it's nearly non existent. I need to move both pups toward the G string but I'm not quite sure if that will fix my bass pup issue.

Re: 4002 pickup guts
Yes, there is a dead spot in the middle of the pickup, because there is no magnet there. Realigning the pickups should fix the matter.

Re: 4002 pickup guts
In reply to Popes....
It was 42.
Here is a photo..

You can plainly see the wires are different sizes....
The wire measured 1.79 ohms per foot as 42 gauge would.
The customer is delighted with the pickup. It functions as it should.
Please don't disparage my company as you do not know me or my products.
My goal was only to shed some light on an unknown....not get in some childish online fight.
Have fun on the forum!

Thomas, Scott Popes was not trying to disparage your company or get into a childish fight here. He was simply going by the spec he is aware of. 42 gauge wire is a surprise to me as well.brantleyrewinds wrote: In reply to Popes....

I'm glad your customer is delighted with the pickup and all is well. That's the most important thing. Let's all carry on amicably from here, please.

He acted like a know-it-all and got defensive for no reason when his knowledge was questioned. A very hostile way to treat people who come to this forum in good faith, the disparaging comments about his business were unwarranted.rickenbrother wrote:Thomas, Scott Popes was not trying to disparage your company or get into a childish fight here.

Re: 4002 pickup guts
Pretty sure Scott can be forgiven for thinking someone overlooked that RIC uses a different gauge of wire instead of them discovering a real divergence to 42 AWG for a rare type of pickup. Apparently they were following the Jazz Bass pattern in more ways than one, but this is a big shock to all of us and a cool one indeed. Yet another possible reason I may like the 4002 pickup's sound so much. No need to point fingers--especially within the thread. If you want to get personal at least limit it to a PM.
Re: 4002 pickup guts
Here's a totally dumb question but I'll ask anyway. If I have a 4004 pickup rewound with 42 gauge wire and install it in a J position, would it sound like a 4002?

Re: 4002 pickup guts
I would doubt it, There is the magnet structure and coil shape to take into consideration as well.. However the simple act of using parallel wiring on the HB-1 would be a good start..ilan wrote:Here's a totally dumb question but I'll ask anyway.

Re: 4002 pickup guts
To redirect my thread back toward fun, here is a sample of my old 4002, which Tom repaired for me. It sounds great! You can really hear it pop on the intro.

Re: 4002 pickup guts
Technically, the statement that we've never used #42 wire in our shop to wind pickups is still a true statement. That's because the coils for the 4002 were wound by an outside vendor, the same shop that produced our amplifier transformers.
Honestly, I have no knowledge of nor have easy access to any records which might show what the original wire spec was.
However, I do have this: On a day when things are slow and/or the issue is more important, I might just unwind one of the dual coils and find out.

Gott in Himmel!!! The mother load!! So what other "gems" does RIC have tucked away inside the secret vault? Based on the above foto, I'd bet that box is sitting next to a pen of unicorns and guarded by the Bigfoot, the Loch Ness Monster , and a Yeti!johnhall wrote:Technically, the statement that we've never used #42 wire in our shop to wind pickups is still a true statement.
