Quick question regarding modifying a 5E3 with a phase inverter grid stopper resistor.
I am preparing to start my first amp build with a Mojotone 5E3 kit and I have been doing some reading on Rob Robinette's site for possible mods I might be interested in trying out. A very simple looking one is the addition of the 470k PI grid stopper resistor above that is supposed to get rid of unwanted PI blocking distortion at higher gain. I want any mods that I do to be easily reversible so I always have the option for the stock circuit and Rob suggests changing the 470k resistor to a 1M linear "sweet" pot to let you dial in resistance to taste, or turn the pot all the way up for a stock sound. That sounds great, but I'm thinking I would rather have a toggle switch instead of having to try and hit the same spot on a pot any time I want to go change my setting. So my question is this: If I were to put in the 470k resistor exactly as shown and then run a wire with a SPST on/off toggle switch beside that resistor going to the same pin and eyelet would that accomplish what I want? I know when the switch is off the signal would have no other choice but to go through the resistor, but when the switch is on will the lower impedance path be enough to bypass that resistor and sound stock?
