Help me choosing please

No need to be sorry. I wish I could speak and write another language.
What are you looking for in a Precision bass, the classic sound?
If so, I don't believe the Blacktop would be the right choice...nice bass but humbuckers instead of split coil pickup.
I've been wanting this one for quite some time.
Thinner Jazz neck, P and J pickups...and it's active.
Fender Deluxe Active Precision bass...$699 or less. Quite a variety of tones with this one...one of the most versatile Fenders made. Of course, some people don't like active electronics...then again, these days some people don't like Fender.

 

If you want some info on the Blacktop, check out our club. There is a lot of reviews of both the Blacktop Precision and Jazz.

American Standard P

that's it, get one !

Sunburst with tort pickguard of course, it may come in other colours hehe

 

Is a Precision/Jazz configuration a viable option? All the "thump" of a P, but a little extra "growl" slipped in by the extra J pickup.

 

I took another look at this post and thought I should mention the obvious; a Blacktop bass, whether a Precision or a Jazz, will not sound like the classic versions they're based upon. The bodies and necks are identical to their Fender Standard (MIM) counterparts, but the pickups are radically different. The irony is that the Blacktop Jazz is probably more capable of getting the classic Precision-sound when it's neck pickup is run solo.

Furthermore, let me stop the P-purists from jumping all over me by saying, "Yes, I know the neck pup is not in the classic sweet-spot." But when I first got mine and demo'd it for my guitar tech, he commented that it sounded like a P-bass when used as such.

So, octa, if you're looking to achieve the classic P-sound, along with the feel of one, the Blacktop series might not what you're looking for.
