In the below picture is the mic input missing a nut.

Does anyone know the size and name of such a nut?


  • Do you mean the one on the most left? It's 6.3 JACK, probably a balanced one (TRS), but may be unbalanced (TS) as well.

If you are referring to the hardware that retains the jack, in the US it is a 3/8-32 jam nut. Most likely.
