Ok, thanks for the help guys. I'll go through the wiring this weekend.
I think i'm going to order a blend pot....

edit.. is it me or do 250/500k blend pots not exist?  :-[

edit².. and why the hell can i only find linear taper blend pots? wouldn't that cut out one pick up at once, instead of rolling down it's signal smoothly?

 I know that dual pots with 2 different values exist, but no item marketted as a blend pot is like that.  As for the taper, I'm not sure, I can see the reasoning for either being better in this instance but never tried it myself; linear is definitely easier/cheaper to manufacture than dual log/reverse log with matching (though inverse) slopes.  Jazzmasters (and maybe a few other offset style Fenders) have a 1 Meg linear volume pot.... and I think some pots on the Lo Z Les Pauls are linear too.

You will be fine with the linear pot, 2x500k - using audio taper for blending will give you a hump in volume when near full, if I remember correctly.

If the single coil gets too trebly with 500k, you can roll off with the tone, right?

Iome

Right.....then i'll need to install a tone pot too.... but i have no place to put it since i also have the toggle switch....i could use a stacked pot....damn, now i remember why i love basses with only one pickup.  ???

Lose the toggle (pup selector?) - it is superfluous with the blend knob; more than that, mutually exclusive really.

You really don´t need a tone pot, I just assumed you had one in there already. If it´s spikey, it´s an easy fix with resistors and caps. Of course, rolling off at the amp is even easier. When thinking of it, the only instrument I need to roll of treble on is my rick 4001.

I've removed the tone controls on every bass I've owned and just "control" that with playing style... ;)

Staring at that event horizon is a dirty job, but someone has to do it; something's going to come back out of it one day...

Me too.Plus i was always bumping the tone pot and wondering what had happened to the sound.
Louder bass!.

It runs the Dimarzio in parallel/single/serie, there's quite some difference in sound.

I too have never used the tone pot, that's why i havent installed one, i was just afraid of all the things i hear/read in the net about using a 500K pot with a single coil.

The 250K/500K singlecoil/humbucker tone-dillemma is no big deal on a bass guitar. Although you might hear it, I think strat or tele bridge pickup might be potentially more spikey through a 500k than a bass pickup. A blend and the toggle will fit the bill.

Again, just flip the polarity on the SC when you hook it up, and stick with whatever gives you most output when using both PU's.
When using the HB in single coil mode, it should be able  to balance nicely against your other SC - like a jazz bass.
Just make sure you take notes when you hook up!

Iome

Thant's exactly what i wanted. A jazz like tone with both pickups as single coils. But i still got the volume loss.
Do you suggest to connect the single coil with reversed polarity?

Sorry for all these question guys, but i'm just trying to understand how it all works...

Granny Gremlin

Yes; whether or not the G is bucked or single, try it with the leads switched to make sure the pups are in phase with each other (loudest and fullest sounding that this combination can be).
