Re: My tone knobs acts as a second volume knob after rewire.
I hope it will solve your issue albeit I really don't see the reason of this diagnosis*. Let us know if it works once the whole thing redone... At least I stand on the idea that a Jumper is missing in the alternate Esquire wiring schematic. If someone from the Duncan staff reads this, I hope it to be useful...
*Foonote about the tone pot: such a control is just a variable resistor allowing a defined amount of signal to go to ground through the capacitor.
If a tone potentiometer is dead, there's only two solutions: either it stays stuck on a fixed resistance (250k or any other value, no matter its position), either it has zero resistance (zero Ohm) whatever is the action on the control. In ANY way, it CAN'T electronically become a volume control, AFAIK.
It's different if the tone CAP....
1- is not wired properly (with its two legs connected to ground, for example, making a short cut and changing the cap in a kind of jumper to ground),
2- if it's defective and/or exhibits some inadequate value, as mentionned above by ArtieToo...
For the record, a 2,2µF cap (= 100 times more than a regular 22nF cap) would cut any frequency above 60hz in a guitar with passive PU's and would therefore change the tone pot in a kind of volume control, since the lowest fundamental frequency produced by a 6 strings axe is 82hz (low E string unfretted)....
All that being said just to be clear, man-in-moon, and not at all to "pontify". It's just that I don't understand how people @ Emerson diagnosticized a dead pot in this case - but I see behind a possible intent to make you spend more money, so I hope they sent you a new pot for free, at least...
Good luck anyway.
