Question about P/J wiring.

[Warrioralex]

Sorry if my English isn't very good, but i will do my best.

I need to know if i can change the wiring of my bass for a different one. The one i have actually is a P/J wiring with 2 volumes and 2 tones ( i think ) with a 3 toggle switch. Can i change the wiring for one with 1 volume, 1 tone and the toggle switch ? If you have the wiring shema, it would be much appreciated!! thank you

What is unclear about it?

Use this. Just substitute the P/J pickups for the humbuckers.

Not sure if you got your answer or if it matters, but it may help if you say which bass you are attempting to rewire, whether it's active or passive. I'm assuming it's an active PJ bass.

95% of the time, PJs are passive.

82.74% of all statistics are made up on the spot.

Probably much more than 95%, actually.

Active pickups are a rarity, and preamps don't tend to appeal to P bass players.

Is it normal to have active pickups on a cheap bass?

 

[Warrioralex]

it's a passive pickups.

Active pickups are relatively rare.

EMG and MEC are the main options, as well as a few Seymour Duncan pickups. EMG's budget pickups are passive, and MEC pickups are very expensive. I believe some Ibanez basses do have active pickups, however. On a cheap bass, you are likely to have passive pickups, with or without a low quality preamp.

wich pots i should use for this shema? 250k or 500k? and what is the green thing with 047 cap written on?

250k is traditional. 500k would be a little brighter.

That's a film capacitor. 0.047uF or 47nF. Any non-polarized cap will work, but get a decent one.

Sorry to hijack, but...

That was my belief (after many hours of TB) but I have this cheap (less than 150€) that uses a 9V but only has wires and the pots inside the control cavity! Is it possible that the preamp is "hidden" elsewhere?

There´s a thread I started about a "refurb" on it here:

To OP: I really do apologize for hijacking your thread!!

If it uses a 9v battery the question would be WHAT is is running? I'd guess the answer is to try to see where the power lead from the battery is going. If it goes to the pickups then they are active and the "preamp" is hidden inside the pickups. Otherwise just try to figure where that power is going.
