The pick-ups of the PU-series are small piezo-ceramic elements with a vibration plate of 0,1 mm thickness in order to get a perfect frequency response and very high sensitivity. They are attached directly to the surface of the instrument with special double-sided, removable tape. Advantages: complete lack of feedback, noise free and high output. No preamp required.

For stringed instruments: the PU-1 with a single element and for a more full sound: the PU-2 with two elements.

For double bass: the PU-4 (four elements).

For drums triggering the TPU element is the ultimate solution.
