Schematic/design tips for a varitone switch?

    I'm thinking about replacing the tone knob on a beater bass with a varitone switch, as a fun project. I had a varitone on my Kramer XL7, and it was very cool sounding- I liked at least three of its five or six settings, and the tones were more interesting than plain ol' treble rolloff. I have the Kramer guts still, and would copy it, but the assembly is tightly-packed and hard to dissect.

    I found some information by searching here and Google, but nothing really straightforward. I understand that I will need to select RC values that will work well in conjunction with the loading of the specific pickup(s) of the bass, but before I even do that I'll need to know how the switch/RC/coil assembly should be wired. I'm NOT going to use it as a combination tone/pickup selector like the Gibson varitone; just a straight inline unit before the output jack.

    Any links, tried-and-true tips, schematics, etc. out there? Thanks!

    bump? Seriously, if you even know a better place for me to ask this question, please let me know.

    Years ago, Craig Anderton published a schematic for a passive tone control that involved a resistor, a number of capacitors and a coil (one winding of a little bitty audio transformer from Radio Shack).

    I'll see what I can find.
