Will they
both always affect the tone, or only the one that is selected?
Reason I ask is because I have a NOS Soviet PIO cap and a NOS Mallory polyester cap - both of which should be very good, and both of which should also have diametrically opposite qualities - and I'd love to switch between them, but if they both are constantly affecting the tone, whether 'switched on' or not, it seems like it would be kind of counter-productive, no? Thoughts, anyone?

Hi Joe,
No, the switch will only connect one cap to the circuit, so only one will have any effect, which one is determined by the switch position.
If I might make a suggestion, put in a 3-way switch, on-off-on (the opposite of a pickup selector). You put one cap on each side of the switch, and attach the middle to where the tone cap connects to the circuit. This will allow you to have the "no tone cap" in the middle position and either the POI or the Malory in the other positions.
