The Shadow SH141 Acoustic Active NanoMag Pick-Up is characterised by perfectly balanced output and, unlike other magnetic soundhole pick-ups, produces a very clear and crisp acoustic sound. A low-impedance output and a fully shielded housing make the SH141 completely hum-free. Installation is simple and takes just a few seconds.
The SH141 comes with a stereo end-pin connector for permanent, ‘internal’ installation. A detachable 4 m (12’) Quick-Mount cable for temporary ‘external’ installation is also included. The electronics are powered by two 3 V batteries and are characterised by extremely low power consumption.
This is a really good pickup system that punches well above its weight price wise. There's no volume control which might be a slight mark against it but if you use an EQ pedal with it it has all the flexibility and sound you'd ever want.
