cap wiring queery for jazz bass

[tom skool]

Any ideas why the cap on my columbus j bass goes inbetween the 1st lug(going clockwise)of the tone pot to the 3rd of the bridge vol pot?

The rest of the wiring is standard according to the diagrams I've found and cant find any diagrams where its done this way. Does it make any difference? If so what?

its a .047 cap and the pots are 500k.

Also if A is log and B is linear. what is D?? my tone pot says D500k!

cheers
tom

Can you post the circuit diagram?
Or maybe some pics of the wiring?

its basicly this but instead of the cap going from the 1st lug to the pot body it goes to the 3rd lug of the bridge pot

[Grangur]

Do you mean it links with the black wire from the pick up? If so the capacitor in that circuit is in series with the tone capacitor linking the signal to earth. This is quite normal.

I can draw this for you as a circuit diagram, but not right now on my phone

no, the other one. On this diagram it would be the lowest lug on the bridge vol over to the right hand side lug of the tone as shown.

Are you talking about the wiring on a brand new bass from a shop?
Or is this a 2nd hand bass where someone may have "upgraded" the elects?
Does the tone pot work/function well as it is?

Over about 3 years of buying 2nd hand basses I've found most have caps wired in the wrong place, so the tone doesn't function. The other thing folk do is put in 500K pots where 250K should be used.

If you mean like the diagram below then when the tone pot is fully up the resistance of the tone pot will be in parallel with the capacitor rather than being in series (as standard). I'm not sure what effect this has but the cap isn't connected to ground so the signal should retain treble. When the tone pot is fully rolled off the capacitor is effectively bypassed so there will be no treble roll off. Does the tone control in your Columbus actually work?!

Volume: output:input:ground (its up to you to get it the right way for your numbers but both ways work)
Tone: cap(ground) :input (don't care were you put them as long as they are next to each other, so one HAS to be in the middle)

If you're looking to rewire your Jazz, I'd suggest you could do a lot worse than to wire it as shown in the circuit diagram you've posted. It's a standard, tried and tested circuit. It certainly won't blow anything up.

If I understand you right, its electrically the same thing as that terminal n the bridge vol is at ground anyway. I take it its working, sowhy worry ?

Rule No.1 in my book. If it aint broke, dont fix it.
