A simple question.
Impedance aside, on a typical situation where there's an output cap and a Volume pot in series with it, it forms a high pass filter. Well, does this filter change depending on where the pot sits, or is the series resistance in the audio path added to the resistance tied to ground?
If we're talking about just the standard cap + pot to ground, the voltage division changes, but the overall resistance of the pot remains the same. So no it's fixed in that regard, that's why you get the 'high cap' across pins 3 & 2 in amps etc.

So, the cutoff frequency remains the same, no matter where the volume sits!?
I was reading about the Fuzzface technology on a website and it said there that the cutoff frequency changed depending where the Volume was sitting. It is confusing as I thought it wouldn't make any difference, in terms of setting a cutoff frequency.
