What is the purpose of the 1k resistor between the volume pot and the output? is it different from just keeping the volume pot in such a position that there is an extra 1k between output and C2?
Thanks for the question.
The 1k resistor between the wiper of the level pot and output is a signal current limiting resistor. It's there to limit the signal current should the output become grounded. It also functions to minimize popping with true bypass switching.
If you build the circuit, please leave you experience with it here as I would love to hear it.
