I have been very happy with my Baggs radius pickup which I have had about six months now, and sometimes use with the Baggs Venue preamp to give it more volume and some EQ for my Washburn 118 mandolin. It reproduces the acoustic sound of my mandolin accurately and I am pleased with the results when I record. That's the test! Piezzo pickups sounded cold and metallic, too much like an electric guitar. This gives the woody acoustic sound of the mandolin, which is what I want. This pickup is also designed for those who don't want to make any structural modification on their instrument, if they have an expensive or vintage model.
