out of phase

[garry warrington]

Just added a nice creamery jazz bass pickup to my Jap Ibanez blazer.

This sounds great on its own, but terrible ( out of phase?) mixed with the P pickup

it may be out of phase, also the p pickup is louder. How can i fix this?

Reverse the connection for one of the p/ups (The Creamery, as it's the last one in..?). Just switch 'em over and try it out again. 'P' p/ups are often louder, as they're fed by a great string movement. You could lower it a bit, or raise the jazz..? Up to a certain point you just have to live with it.
Hope this helps.

why reverse the Jazz pickup and not the P ? do u mean swap the hot for the earth on the pot?

Swapping the hot and ground is how I read the advice given and since you've only just installed the jazz pickup I also think it makes sense to do it with this one (don't change anything with the existing P).

It doesn't actually matter which one, as there's only two possibilities; they're in phase or they're not. Which ever is easiest to swap, but as you've just done the Jazz soldering, I'd have just swapped them over, unless there's a real problem, such as access or such.
Yes, it's simple with a 2-wire p/up, as there's only two joints to re-solder. A bit more tricky with 3- or 4-wire p/ups; I was assuming that's not your case, so... Don't over-think it, just swap 'em over and see if they work better like that. Let us know how you get on, please..?

Curiously (or perhaps not), loudness depends on the velocity of the string motion, not the displacement . But a greater string movement has to have a greater velocity, so it is sort of related.

Possibly, probably, certainly, whatever... The p/up gives out less signal the further one gets from the mid-point. Almost over the bridge (or nut..?) one gets pretty well nowt. In passing, and for the same reasons, a p/up will give a progressively weaker signal the further up the neck one plays. Right at the end of the fingerboard, a neck p/up is not getting much at all..! Is that important, though..? I doubt it.

You're right. Ears work better than science. Wait a minute, don't ears work by science? Now I've confused myself

Yes guys, you advice was good. Swapped the cables around, the bass sounds great(the creamery pickup is excellent) both pickups together give a reall funky J bass vibe.

I may even change the stock precision style pickup to a better quality,maybe another creamery. He is local to me..

Thanks
