zaobera sa to aj tym, ako to technicky funguje, no su tam z toho vyvodene aj pre hracov pouzitelne zavery typu

"You start to see how interactive this shit is:
The resistance of the treble pot only affects the ‘treble filter’.
The resistance of the bass pot affects the ‘bass filter’ and the ‘treble filter’.
The resistance of the mid pot, last in the chain, affects all three."

"quite aside from the effects these later pots, Bass and Mid, have on their own bits of the sound, their setting already affects the high-pass filter at the beginning… determining the range of what falls under ‘treble.’"

"The mid knob, in addition to its other duties, controls how loudly the entire signal leaves the tone stack."
