So instead, I would rather just include a mute switch on my amp.

I'm guessing this is the best way to do it, unless anyone knows a better way.
C6 is the input to the PI.
Would like to avoid any popping sound if possible.

The pot is already across the switch contacts.wpaulvogel wrote: ↑Fri Dec 20, 2019 2:21 pm I’d experiment with a resistor across the contacts between 10-22Meg to eliminate popping.
Academic note: this would be true if life was simply in terms of power-on-hours; but it's not that simple. It is true that hours of electron emission and hours of active cathode bombardment do add up to poison cathode emission, and hours at temperature do erode and eventually open heater filaments. But for something like a 12AX7 left on continuously, this may be a huge number of hours, the equivalent of decades of continuous operation. For power tubes, the thermodynamics are worse, but the number of hours of life when idling at current may still be many years altogether. One other big factor in lowering life is the number of thermal cycles and current surge cycles.
What if someone else needs to use my amp? (Which happens time to time!) I would prefer something more universal
That may seem intuitively obvious but I don’t think it’s correct.
