Passive tone control

[kasbrey]

I've recently fitted a Noll active blend circuit in my P/J and wired the master volume after the circuit with a passive tone wired in the usual (for passive) way.
This however results in no treble bleed off.

Is this because the signal path is now buffered?

I've tried a different pot/capacitor etc.

I used to have some active EMG's that worked with a passive tone.Am I doing something stupid?

Maybe I'm wrong, but I would have thought that wiring the tone round the output jack terminals would have worked.

Anyone know how to wire a passive tone (eg Sadowsky's VTC) to an active bass ?
