Warwick Rockbass, active pickups no preamp!!!

I've been wondering what if I remove the onboard preamp from my Rockbass Corvette Classic but not the active pickups.
But as I don't want to damage any electronic parts inside the cavity I thought I'd better use new pots.
Seymour Duncan recomends for their active pickups 100k pots but Warwick has a complely different layout for their rockbasses so my question is what should I use, are 100k pots ok for my bass or I'll have to use higher or lower values?

Active and Passive Bass Pickups

Umm ... the warwick diagram shows a passive setup. Are you using the original Rockbass pickups? If so, you don't need the preamp, and you can use a control assembly as illustrated in the warwick diagram.

If you have active pickups, you'll need a preamp and whatever pots the pickup mfr recommends (or something close).

If there are red wires going directly from the battery to the pickups, you have active pickups.
If the pickups just have a hot and a ground, you can consider them passive.

I'd use 25k pots for the volume if active pickups.
I'd go with 500k pots if they are passive pickups.

As I have mentioned above they are active pickups.Sadly there is no active pickup only schematic, everything on the Warwick site has the preamp on and since the pickups are quite expensive I 'd like to give them a shot before I move on to something else.
My problem is about pot values, thanks Rojo412 by the way, but I also need values for blend,neck tone,bridge tone, so additional info would be appreciated!

Look on EMG's website. I forgot if blend pots use strange values or not, but they'd have a diagram.

You mean that I might be able to try the existing values without the preamp?Right?
