What is your definition of an equaliser? How much control do you want
to have? How exact should the control be? How much distortion is
allowed?

For a guitar with at least two single coils you don't need an RC element
to get a tone control. You only need two switches. Just use on of the
coils, use both coils or use both and change the phase of one coil. So
two coils and two switches = 4 sounds. Instead of using 2 switches, you
could change the distance between a pickup and the strings, then you
could consider the "equaliser" would be a screwdriver, but actually
it's physics. keywords are "time domain", "insulating material" etc.,
e.g. move your hand in front of your mobile's speaker to get a wah-wah.

Do you need a processor and RAM for an equaliser? For a digital
equaliser you need a processor and RAM. For an analog equaliser you
don't need it.

To control the tone you need a tone control.
