When we first debuted the original "Dualie" pickup approximately ten years ago, it was designed to be used on acoustic and classical guitars.......And then a funny thing happened: musicians discovered that they could stick the Dualie onto just about anything and that it worked and sounded great. Basically, if you have an acoustic instrument,such as a ukulele, then the Dualie will work well on it.
Through the use of twin piezo elements we have been able to greatly enhance this pickups' resistance to feedback, particularly when compared to other surface mount transducer pickups. It is light in weight (a couple of ounces), and does not inhibit top movement or vibration
