    Will this be a problem? What effect will it have on the system or will it just roll off some highs or what?

    Ps. Referring to EMG DC40 pickups with a Bartolini HP 4.7

    It will work like an on/off switch.

    I could be wrong but it may need a 25K blend pot

    Adding (any) 2 pots together halves the resitance- 50k + 50k = 25k.
    Lesser total resistance results in less highs avail typically.
    50k pots have been used w/EMG's preserving more high end if that's what is wanted-
    it can always be rolled off.
    Haven't tried 250k pots w/EMG actives, tho-

    this.

    all one pickup, all the other pickup, and both pickups full-on together will sound fine, but forget about any shading or blending, you might as well just put a 3-way switch in there.

    ^the 3 way switch effect doesn't bother me much seeing as I always run in the middle with both pickups, but I am concerned that it might be causing unbalanced high end. It sounds ok but a bit brittle in the top end which could also just be the ceramic sound of the DC40's?

    It won't do any damage to the pre or pickups though right?

    Won't cause any damage, and tone pot can be rolled off/ caps can be changed, also.
    Better with a 50k or 25k pot, tho.

    the blend isn't causing a tonal change, that's just what DC 40s sound like, aggressively clanky high end.

    and yes, none of this will damage anything.

    Thanx WalterW :) I think you are right, a pickup change is in the future for this bass...
