Theres your answer. You have a mid boost guitar and a weird pot that snaps at the end. Definitly not a coincidence.
It sounds like your one tone pot is actually the mid boost control notched at one end to turn it off. From what I know of fenders you should notice something if this is true. Start with both tone controls turned clockwise. Now play your
bridge pickup and turn the regular (not gold) tone knob down and it should sound muffled. Now try it on the necck pickup. If that same tone knob works for all 3 pickups then theres no need for a second tone knob with a notch. That gold one is your mid boost controll.
