Business as Usual! I hope you, your families and fiends are safe and well in the current situation.  Silverfish Harmonicas are still open for online sales and shipping of orders with trading continuing almost as normal during the Covid-19 pandemic crisis. However there is a slightly extended lead-time of 2-7 days dispatch delay due to a once-weekly shipping arrangement for all orders. Just as a precaution the microphones and their cases are disinfected prior to packaging for complete piece of mind.  Thank you for your patience during this difficult period – normal trading arrangements will return as soon as possible! Apologies for any inconvenience that may be caused.

Harmonica Microphones
There is a choice of either dirty or cleaner sounding Silver Bullet harp mics. The two contrasting dynamic elements also reflect different output impedance (Z) and have differing amplified sound characteristics. They will both match most amplifier or PA rigs that have a high impedance input-socket.

Silverfish harp mics are available in two basic designs: the “Standard Harp Mic” which is modelled after the vintage mics featuring a terminal volume control and angled base-mounted jack-socket with a low form-factor; and the a range of mics with a terminal jack-socket and minimalistic side-mounted volume control. Both designs feel good in your hands, are enjoyable to use and easy to cup and hold – even with sweaty hands. These mics look extremely cool on stage when, as a harp player, you may be the centre off attention! 

Each genre of mic (clean or dirty) share exactly the same performance characteristics and deliver a rich, full sound that responds to cupping and pressure changes and are technique- sensitive.  

In summary:

For a cleaner sounding harmonica mic – choose the 4KΩ dynamic microphone. This is a microphone for the  harmonica player who is looking for a cleaner sound – providing a  mic that is rich in tone, ideal for playing cleaner sounding blues, and especially suits playing melody, country, funk, reggae, soul or chromatic harmonica.
For a dirty (Low-Fi) distorted-blues sounding harmonica mic
– choose the 50KΩ dynamic microphone. This is a high-Z  mic for the serious harmonica blues player – providing  a powerful and dirty low-fi sound that is rich and fat in tone.
