Treble bleed for Bart NTBT preamp

[gimmeagig]

Hi,
I have a bartolini NTBT 18V preamp in my moon bass.
When I roll back the volume I'm also losing quite a bit of treble. I've had a treble bleed installed on another bass in the past. But I don't remember exactly what that entailed. Some component hooked up to the volume pot. That's all I know LOL and that it worked. ...
Can you guys tell me what I might need. Anything to watch out for... Maybe even a little schematic so I can pass it on to my local repair guy.
Thank you so much
