I installed the 500k CTS version on a dual humbucker guitar and I’m noticing that when the guitars volume is decreased the clarity is there as advertised but there is an additional bump in the mid range almost like I have a wah pedal on in the “toe” position. I’ve used/tried several other TB circuits and haven’t ever noticed a mid bump. Is there something in this item that might be causing that?

This is a passive circuit, and it may be that you need to adjust the internal trim pot to taste.
I did try lowering it all the way down to see if it eliminated the mid boost I was getting and it was a little better but not much.
Are you sure it is hooked up and adjusted correctly?
Is this the "Duncan" or the "Kinman" wiring?

Both the "Duncan" and the "Kinman" treble bleed circuits are simply a cap/resistor combination and can not be adjusted to taste like this unit.
The Kinman style is with the resistor in series. I believe this is a parallel cap/resistor combination.
I see this attaches to the Volume pot as an adjustable treble bleed. Does this mean I do NOT need a capacitor on my Tone pot? Thanks!

That is not the case. This simply retains the high frequencies when rolling down the volume knob. If you want a funcioting tone knob, an additional potentiometer as well as a capacitor will need to be included in the circuit.
