Microphone specifications

Customise your Silver Bullet harmonica microphones

Microphones are supplied in a variety of styles that provide you with a choice of customised look and as either a bullet mic with adjustable gain or as a very small bullet microphone with no volume control.
Microphones are available in a range of custom coloured fascia’s (or just go for the lovely hard-wood finish) and available in two sizes:

  • Midi – small bullet mic with no gain | fits mic-stand
  • Standard – bullet with volume/gain control | fits mic-stand
  • Impedance matching

    The 4KΩ and dynamic microphone perform well on most amps with high impedance sockets and when used with PA systems. This therefore represent a safe bet for a Silver Bullet if you want to avoid getting technical on your impedance matching! Sub-optimal impedance matching (ideally amp input should be 10x that of the source mic’) may be compensated for with adjustment of microphone gain and amp settings or use of a pre-amplifier.

    What kind of Silver Bullet Harmonica Microphone should I buy?

    The choice of harmonica microphone may be a little daunting. If you are struggling to select the right harmonica microphone or are unclear on the difference between the versions of Silver Bullet available (different impedance: medium or high-Z) or even what impedance is about (a measurement of the resistance of the microphone – divided into low, medium and high measured in ohms or Ω) don’t worry! Hopefully this summary of the Silver Bullet range will help you understand their different characteristics and help you select a mic that is best for you.

    If you don’t know the specification of your amplifier or can’t be bothered with that sort of thing – both the 4KΩ and 40KΩ dynamic microphones perform exceptionally well on most amps and when used with PA systems. Although perfect impedance matching is idea, sub-optimal impedance matching may be compensated for with adjustment of microphone gain and amp settings or use of a pre-amplifier. Of course to get the very best out of your microphone in terms of volume, sound quality and performance you ideally need to ensure that the microphone you plug into your amplifier is matched to an input that is ideally about 10x that of your microphone. If in doubt please contact Rick for advice – who is always happy to advise.
