Yep!

It means that in all probability the slider in the buzz control is not making contact with the resistance element and when that happens, it opens the cathode on the audio detector and your sound goes out.

This either indicates a dirty control or a bad control.

It is also possible and quite probable that the sweet spot on the buzz control is in that open spot.

To test the control:
Put an ohm meter on both ends and it should read 600 ohms. Put an ohm meter on the cathode end and on the slider and when the control is rotated, it should vary between 100 and 600 ohms with no open spot.
