King Tone Guitar Switch

[Elijah-Baley]

Hello,
sometimes I like to jump back to some of my old topics. Today, I’ve been thinking about the King Tone rotary switch for guitar, the Classic version.

This is the link to the switch: https://www.kingtoneguitar.com/product/king-tone-switch/

It’s not a tone cap switch, but something that changes the overall tone of the guitar making it bassier, brighter/crispier, smoother...
It also includes a treble bleed with many different settings.

There are many treble bleed circuits we can use or try, so I’m more interested in the tone/sound changes themselves.
I assume it uses capacitors, maybe resistors, and... inductors?

I’d like to get an idea of what the schematic might look like, or some possible approaches to achieve this.

Thanks.

According to Reddit it's basically a varitone. The picture seems to confirm that. Unverified though! $99 seems pretty high for what this is.

Better vibrato tracking. String bending becomes more articulate.

Oh man, that's just delicious bullshit marketing talk that I almost want to change my signature, but I don't think it works quite as well without context.

From the Kingtone picture I don’t see where the inductor would be, assuming it’s a 1.5H inductor: it would be pretty bulky. So maybe it’s even simpler than the varitone?

I didn't find the side of the PCB with the parts.
Ok, that could be just a cap tone switch.
But I see five cap and five resistor. We could assume something else?

What does “vibrato tracking” even mean?
I’ve only ever heard “tracking” in reference to pitch-shifter/harmonizer/octave type stuff. What could you possibly be tracking when you’re physically wiggling a string around…?

Is it just five fixed RC filters on a rotary?

The descriptions of the six modes seems pure marketing and totally nonsense.

With a rotary you could have a mix of low-pass and high-pass filters. Might sound cool
