3-band Baxandall

Hi everyone,

I'm thinking of including a 3-band Baxandall tone control in my new preamp. All the examples I've found of such a circuit are using a different value potmeter for bass control than for treble and mid controls. Because this amp is going to have digital pots I want them all to be 100k.

Does anyone know where to find schematics for a 3-band Baxandall using only 100k pots?
