I use this on a home made banjo bass or bassjo if you prefer and it works pretty well.It keeps a real banjo sound and deals perfectly with low end sounds of a bass.I don't know how it works on a real banjo but I suppose it does the job well (it's made for !)
This pickup is designed to fit underneath two of the feet on a guitar bridge. I tried this and didn't like it at all. I took it off, removed the resonator and used Everbuild Mammoth Powergrip Double-Sided Tape (A hearty product plug for a superb and essential product) to stick it to the skin underneath the bridge feet. Now it sounds good and works well. The piezo pickups are small and don't show through the skin.
I don't usually chuck in gratuitous plugs, but every guitarist should own a roll of Powergrip double sided tape. You have been told.
