I needed to replace my volume pot on my Road Worn recently. I like to do volume swells but with the new pot, it's impossible. It's way to stiff. Does anyone have a remedy for this? It's a CTS 250K pot. One more thing, the threaded shaft of the pot is too wide for the knob, so the knob sits higher off the baseplate than the tone knob. Maybe I just bought the wrong pot?
