I want to install an external V-Size pot adjustment to my cab. I would like to do so without having to remove or alter the existing pot. I am hoping it would work to have an external pot that connects to the existing pot in parallel to allow me to make tweaks. Would this work? Any suggestions on type of pot to use? And how would I wire in the new pot? I am thinking I would wire it same-to-same. So + to +, Grnd to Grnd, and Signal to Signal.
It is a Wells Gardner K7000 series. It appears that the V-Size pot is 200 Ohms. I will have to check the range of resistances I want to get with my multimeter, but I think adding a 500 Ohm pot would give me the ranges I need?
