I have a Vaquero that someone replaced the factory ground balance pot(?) with a 12 turn. Does anyone know where I can get the original part or know what the part is so I can get an aftermarket one. Even better can I use a 1 turn like in the older Fisher models??. I've never known any advantage of the Tesoro 2t over the Fisher 1t. If anyone would like to trade for the 12t that would work too, PM me. Thanks for the help.
