The KNA UK-2 Ukulele Pickup is a great choice for musicians craving the natural sound of their uke without an invasive and irreversible setup. A wood-encased piezo sensor is mounted under the strings on the rear of the bridge. After installation, connect a cable which includes a male 3.5mm TS jack to a male 6.3mm TS jack, then use the volume pot to control the level of the signal. Oxygen Music stocks a range of pickups and accessories including the UK-2 ukulele pickup from KNA.
