Dirty-sounding microphones

Silver Bullet dynamic – high impedance harmonica microphones


A slightly more powerful microphone with a courser, strong, rich and full sound across the dynamic range but with a dirtier distorted sound. Headroom slightly lower, and sensitivity slightly higher than medium-z (clean sounding) microphones.

Silver Bullet | Dynamic High-Z 40KΩ

For a dirtier distorted-blues sounding harmonica mic (and heavier crunch distortion at high gain) – choose the 40KΩ dirty sounding dynamic microphone

The microphone has a really “hot” signal that is packed with full harmonic content and great tone with perfect base and mid-sound without treble. The 40KΩ offers the highest sensitivity of Silver Bullet range with slightly lower headroom so if you like crunch distortion and a lovely dirty blues sound this is the microphone to chose. Turn up the gain to drive the mic’ and achieve various degrees of distorted, crunchy classic “blues” harmonica sound-ideally applying a bit of reverb from your amp. At lower gain the mic has a slightly cleaner sound across the harmonic range. Dynamic microphones have proven reliability and are ideal for practice or gigging – blues and country harmonica performance. This mic’ needs to be matched to a high (400KΩ/0.4MΩ) impedance sockets on your amplifier.

Check out Ben Hewlett’s video review comparing the 4KΩ (clean) and 40KΩ (dirty) Silver Bullets – which includes some cool playing showcasing the lovely tone of both these microphones when played by an expert!.

See Tim Douthit’s video review and sound sample of the 40KΩ dynamic Silver Bullet comparing it to the classic Green Bullet.

These high impedance, dirty sounding silver bullets are awesome little microphones with technology and craftsmanship that delivers a compact design with many of the features a harmonica player wants and needs and is very technique sensitive.
