The needle ensuring the electronic connection between the capsule and the preamp tends, as time goes on, to unscrew by itself. It also tends to superficially oxidize, and requires from time to time a cleaning with an alcohol solution.
Take care to keep clean the tight grille which protects the lateral events; because in case of dust or dirt accumulation, the acoustic impedance presented at the sound wave by the tube is modified by it and consequently the microphone directivity and response are also altered.
The previous internal nylon joints of the VdB boompoles tended to inflate with water. Before any storage, thus think of well cleaning your pole after deployment under the rain or in very wet condition.
