KNA has been working for the musician for years with an instrument without the possibility of reinforcement. The company KNA started from a loner from Bulgaria, Vladimir Hranov. A man who was always fascinated by radios and the transmission of sound. He has used the knowledge he has in this to make guitar elements.
From microphone to magnetic elements KNA has it all. The KNA Pickups BP-1 Element for Banjo is an easy-to-install piezo element. You clamp it on the bridge and you have an input on the other side. Here you plug your cable in. The vibrations of the bridge strengthen the banjo. So you can connect it or a PA or an amplifier. What KNA does very well is that the characteristic sound of the instrument is not lost.
