With a diameter of just 8 mm including a structure-borne silencer, the WP-1X fits into almost all mouthpieces for woodwind instruments. Especially for very deep instruments such as bass clarinet or baritone saxophone, which are very difficult to pick up with a conventional microphone, our WP-1X is the perfect solution. A big advantage is that in the built-in position in the mouthpiece, frequencies can no longer be erased even with the highest tones. This results in a very balanced sound in all ranges. Absolute uniformity over all tones of the woodwind instrument and a sound pickup without feedback are the best prerequisites for stress-free monitoring. For maximum freedom of movement, the system can be operated with almost all guitar wireless systems. These advantages guarantee the best conditions for uncompromisingly good stage performance.
