The ‘OUTPUT LEVEL’ control on my Field feels very loose. I haven’t tried pulling the knob off or opening the Field to look at how it’s mounted. The bottom of the knob is almost flush with the surface of the panel so you can’t see anything beneath. As opposed to the 1-8 knobs which are separated and you can see the mounting nut.
Any advice-instructions? Is this a known problem or just the way it is or broken?
