JB with 250K pot

Re: JB with 250K pot

Done! I just wired in a tone pot set to all the way open and stuffed it away in the control cavity. Much better! But still the tone quest continues...
Thanks to everyone for their help and views on this.

What's your actual setup?
JB with 250K Vol and 500k (?) tone
'59 with 500K Vol

Instead of the Pot all the way open you can use a 500k resistor.

Btw. which resistors to use? I think there were better with lower noise?
I want to make a "Seymour/Bright" switch for my JB.

Yeah, I have 2 volumes now (250K for JB and 500K for '59) and one tone 500K pot stuffed away in the back. I like this better than without a tone pot.
I still had some pot's and caps floating around my room so I just took the safe route, it's very quiet to my ears but that may also because I shielded the entire control cavity with aluminium foil tape. I'm not shure about the resisitor thing but I want to try that too. Do I need to wire a tone cap in parallel with the resistor or can I simply follow the schematic that LH_ gave me?

Edit: If I'm not mistaking a resistor with a green, black, yellow and gold or silver ring is a 500K one.

Re: JB with 250K pot

I can't look at the schematics coz i hadn't installled acrobat yet under my linux....
But you just have to wire the resitor in series with the cap. When the Pot is on ten between #2 #3 plug it is like a resitor with 500k.
I just mentioned the resistor because maybe you don't want to have a pot lying in your control cavity.

How sounds the JB with 250K and tone? Clarity?

Re: JB with 250K pot

Well small changes can make big differences, I have no idea how to explain it correctly but this pickup was made to be wired this way. Sounds very balanced now with the right amount of everything. It sounds 'right'.

Btw. the schematic you couldn't read was of a telecaster where the resistor was wired between the hot and ground.
You say wire the resistor in series with the tone cap? Not parallel? Not shure what you mean with #2 and #3 plugs.
I rather don't have a tone pot lying around the control cavity indeed.

Re: JB with 250K pot

I meant the two plugs (?) which are connected normaly on the tone pot. I think it is the second and third pin. You simply replace the pot with the resistor

If you wire it parrallel you have two effects at all. It would be like if you had the tone control on 0 and have a 170K Vol pot or something.
It goes like this:
hot -> resistor -> cap -> ground or
hot -> cap -> resistor -> ground
it doesn't matter.

Re: JB with 250K pot

Yes I think I get it now. Just replacing the pot of course. (It's sunday, so my IQ is down to half as usual, sorry) I just found a 720K resistor, have no 500K ones around. Need to go shopping tomorrow, ah well for now it's close enough, let's see what happens. Thanks for the help Marcel!

Re: JB with 250K pot

I can see now why Seymour Duncan designed this pickup originally for the tele gib with 250K pots.

You know that's a myth that was refuted by administrator Evan Skopp .

Evan once said that the JB was never called 'Jeff Beck' and the the JB isn't the same PU that went into the original Jeff Beck '74 Tele-Gib that Mr. Seymour Duncan made for Mr. Jeff Beck.

Really? The link didn't work for me but I'll try a forum search.
I still think the JB sounds better with a 250K pot but that's just my ears.
I hope I can find something with the search, otherwise I am eager to hear the story.

The link was just to Evan's profile ... not sure if all the old threads are still available.

With a 500K (not 250K) pot you'll be letting more high frequencies go through.

That's what's great about the JB ... everybody has a different take on it.

PS: >>> Major Edit work Done

With a 250K pot you'll be letting more high frequencies go through. Makes for quite a lead PU but at the expense of your rhythm sound. Put a 1 mg pot with the JB ... thick rhythm tone but no harmonics.

Sorry but I think this is wrong or i understood something wrong.
The 250K pot is used to tame the highs.

Re: JB with 250K pot

Yeah my intention was to tame the highs on the Jb by wiring in a 250K pot. I also have the understanding that a higher pot value will let more high frequencies through.
I think that using a 250K improved the rythem sound and the lead sound just stayed the same. (still singin'!) Not shure about the harmonics but I don't think those are unaffected.

That is what it did for me

Sorry ... my mistake. :smack:

Higher POT value lets more high frequencies through.... d'Oh!
