Type: electret film
This new pickup for double bass comes from Russia, and is placed under the foot of the bridge. No piezo is used, but an new electret film. This film allows a thickness of only 0.5 mm. In addition, the sheet is flexible and totally even, and fits the curvature of top and bridge feet perfectly.
Due to the placement on the bass’ top, the sound of the APT-flex is round and powerful for both pizzicato and arco.
The electret film sensor is shielded with copper foil, and has a rigid cable joint. The jack is attached to the tailpiece by means of a cable fastener or a plastic clip.
