Shadow SH330 passive acoustic guitar soundhole pickup, in natural maple wood.
This single coil pickup features a beautiful maple wood case with a natural finish and is vacuum waxed and sealed in epoxy. A  generous 12 foot (4m) noiseless cable is fixed from the pickup and ends in a standard 1/4" jack plug. It installs very easily and can be detached at any time. The pickup can be rotated in the soundhole to allow fine tunings of harmonic response. Since 1971 Shadow Electronics stands for high quality and absolutely reliable pickup systems for many stringed instruments.
