To use the no-load for a volume you wire it like a controlled bleed to ground.

To use the no-load for a volume you wire it like a controlled bleed to ground.

I have not used this, but I have read the highs are rolled off a little as the volume is decreased (it's a 250K pot). This may be a good thing here.
When the control is full counterclockwise there is no resistance so the signal goes to ground (no sound).
As the control is turned clockwise the resistance increases and the volume goes up.
At full clockwise the control clicks and disconnects from ground and the full signal goes to the jack in basically a straight connection.
don't believe everything you read on the internet
it won't be "cleaner", it will be brighter. with fender pickups, it can easily be too bright, sounding tinny (to use your term) and brittle. i myself like the extra edge and "slice" of 500k pots (especially with a little sansamp grind), but no load at all can get harsh and unpleasant.
also, a cap without the resistor would be like a tone pot on zero, i.e., full mud.
People think of the tone control two different ways: full on cutting treble or full on letting all the treble through.
I think of it as full on letting the treble through because the resistance of the pot is at full and blocking the bleed through the cap.
With a cap and no resistor it is like having the tone control off and cutting treble to the max. In this state, any additional brightness you could get from removing the pot/resistor would be inaudible.
Since the resistor blocks the signal from getting to the cap, I don't think you would hear any difference.
Even if you could, you would be counteracting the changes since the 500K resistor would cut fewer highs and the .1uF cap would cut more highs.
I think it's kind of big. With the .047uF you're at half volume at 600Hz and half of that at 1200Hz. With the .1uF you're at half volume at 400Hz and half that at 800Hz.
The last two samples here are .047uF and .1uF:

Nice one Snake, thanks for all your input, its been great
By the way is the tone knob all the way down in the video demo? Just asking as anything that cuts below 900hz sounds really muffled to my ears?
That video is showing the caps straight from the signal to ground, so it would be like the tone control is off (maximum treble cut).
The resistor does not block the signal but will reduce it proportional to the resistance and the current through the resistor.
Resistors by themselves do not have any frequency-dependent properties, only capacitors and inductors do (except for very small non-ideal effects which are usually but not always ignored in engineering). A capacitor and resistor in series can be used to create a passive high pass or low pass filter with the roll-off frequency of the the filter determined by f=1/2*pi*r*c. Whether it is high or low pass filter depends on the configuration (see wikipedia for examples).
The resistor and capacitor here are not an LC filter. The resistor and capacitor are in line from the signal to ground. Maybe I should have put quotes around the word "blocks." When the tone pot is at 250K Ohms it is effectively stopping the audible effect of the capacitor.
if we want to be fussy, it's almost stopping the audible effect of the cap.
if you were to wire a switch to go between "250kΩ on 10" and "totally disconnected", you'd likely just notice a slight increase in brightness when the tone cap was bypassed.
if it was "500kΩ on 10", you might barely notice a change, and if it was "1MΩ on 10", you wouldn't hear a difference.
OK, since everybody wants to pick apart everything I say: why doesn't someone answer his question?
I'm tired of the frustration of not being able to say ANYTHING without people nitpicking me apart.
You all win...
I won't be coming to TalkBass anymore because I don't need the grief.
You guys help people.

Hey snake, dont feel like that - electronics is a science based concept that is difficult to understand, and put into the 'art' of music, hence why nubes like me ask so many detailed and sometimes srange questions...
Everyone has an oppinion or experience about stuff and all info is good. And your contirbutes are just as valuable to me and anyone else learnning how do tackle wiring etc for better sound
