I'm playing with a linestage design and saw Glass Tube audio had a circuit for a 12AT7 which showed a 220K grid to ground resistor in parallel with the volume pot.
I have played with putting it in and I do get more dynamic but also more noise by the nature of having another resistor in there.
Its a simple circuit using a 5689 single half with output transformer. If the 50K pot is loading the grid why would the circuit need another resistor in parallel?
I usually don't see this.
