The -BLACK PEARL- Resonance Control Unit gives you the best possible performance with your favourite String-Instrument as well as for similar Instruments possible..

The BLACK PEARL 120 mk2 Resonance Control Unit is geared towards competent amateur musicians who wish to unleash the hidden potential of their Violoncello and Bass and who also wish to add new found qualities to their instrument.

It is the small-scale entry into the new dimension of Cello- and Bass-Playing with more enthusiasm and expressivness but without the influence of sound-limiting floor resonances.

This makes the revolutionary INSTRUMAGIC resonance concept possible, which is composed of specially selected resonance materials. Here exquisite precious and semi-precious stones, as well as special woods, metals and inorganic nonmetals with defined resonance and vibration properties are sensitively tuned to each other and are also connected to the respectively unique resonance system.


The BLACK PEARL 140 mk2 Resonance Control Unit are particulary appealing to discerning cellists who want to maximise the sound potential and playability of their Violoncello or Bass with our Resonance Control Unit in 140mm Format.

A significantly wider dynamic range, along with an increased expressiveness and a whole new dimension of sound purity, are the special features of the BLACK PEARL 140 mk2 version. Playing a Violoncello or Bass, which is placed on the BLACK PEARL 140 from INSTRUMAGIC, represents both a challenge and an enriching experience at the same time.
