Harmonica microphones - Lo-Fi Dirty Sounding

Dynamic harmonica microphones – high impedance, dirty sounding


A powerful microphone with a courser, strong, rich and full sound across the acoustic range but with a dirty distorted sound. Headroom lower, and sensitivity higher than 4KΩ (clean sounding) microphones.

For a dirtier distorted-blues sounding harmonica mic (and heavier crunch distortion at high gain) – choose the 50KΩ dirty sounding dynamic microphone

The microphone has an extremely “hot” signal that is packed with full harmonic content and great tone with perfect bass and mid-sound without excessive top-end treble. As a harp player you may play close to the edge of feedback in order to get the very best tone from your mic and amplifier. The high impedance and performance characteristics of this microphone provides exactly what you want as a blues player. The combination of a hot mic with low headroom provides lots of scope for crunch distortion and rich dirty blues sound that will blow your socks off! Turn up the gain to drive the mic’ and achieve various degrees of distorted, crunchy classic “blues” harmonica sound, especially when cupped. At sound-check use the gain on the mic to find your sweet-spot with rig/amp settings – balancing amp and mic volume to achieve the desired level of distortion and volume. Use a touch of reverb to achieve a crunchy classic “blues” harmonica sound which is full of tone.

Dynamic microphones have proven reliability and are ideal for practice or gigging – blues and country harmonica performance.

These microphones are high (50KΩ) impedance which should be matched to a high (500KΩ/0.5MΩ) impedance, sometimes labelled as a passive socket on your amplifier. Poorly matched impedance may diminish the volume and performance of the mic. An amp input impedance of at least 10 times the amount of the source mic impedance is advised.

Check out Ben Hewlett’s video review comparing the 4KΩ (clean) and 50KΩ (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 50KΩ dynamic Silver Bullet comparing it to the classic Green Bullet.

These 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 are very technique sensitive.
