Après pas mal de temps de réflexion, c'est Telefunken US qui m'a donné l'idée que j'ai mise en pratique pour les micros
Une boule qui se glisse sur le corps du micro, pour donner un résultat similaire au Neumann M50.

OH YEAHHH!!

SCHOEPS
KA 40 / KA 50 ACCESSORY SPHERES
Acoustically modifies the sound of Schoeps omni transducers
Two sizes, which slip over the capsule and front end of the microphone body
These ball-shaped accessories slip over the head of the pressure (omni) transducers, as shown in the photograph. The KA 40 has a diameter of 40 mm, the KA 50 of 50 mm. They alter the sonic character of the microphone acoustically, as is evident by comparing the graphs of the CMC 62 (CMC 6 with MK 2) with and without the KAs. With the 40 mm sphere, the normally ruler-flat on-axis frequency response curve of the MK 2 is emphasized slightly (max. +2 dB) in the region between 1 kHz and 9 kHz. This effect is stronger still with the 50 mm sphere (max. +3 dB). This is not due to any change in directionality, as is sometimes supposed, but rather to the elevated response plateau which is achieved without sacrificing bass response.

It creates the illusion of closer placement so that greater miking distances can be used while maintaining good ”focus” in the sound. This in turn improves the blend and balance when recording orchestras or choruses, for example. The effect is due partly to an increase in directivity, but mainly to the elevated mid­range response (see frequency response curves. The low-frequency response remains undiminished.
