    Let's say i would like to tap right on a bass pickup cover in order to make it sound. Would a brass/nickel/steel cover be good for that?

    No need for that. Just loosen up the pickup by removing some of the foam or springs underneath, so it can wiggle slightly in the bass. Then tap on it and it will make a thump. That's a classic form of microphonics; where the pickup starts behaving like a microphone.

    Thank you, but i don't fully understand. A magnetic pickup does not catch any mechanic vibration. What kind of oscillation in the magnetic field is produced when lossened?

    If the pickup is loose in the bass, and you tap on it, then the pickup wiggles in relation to the strings. The reverse of the normal operation where the strings wiggle over the pickup. The metal strings moving in relation to the pickup disrupts the magnetic field, causing the signal in the coil.
