For over 18 months VERSUM SOLO was put to the test with more than 100 international soloists and professional musicians in 300 independent try-outs. The result?


The VERSUM SOLO edition offers unprecedented possibilities of combining color, sound and texture. These strings were designed for profound power, ideal response and optimal projection - and they deliver! With effortless virtuosity they are poised to enhance the performances of even the most discerning players and cut through any acoustical situation.

Versum Solo A+D

  • Powerful body
  • Soloistic brilliance
  • Maximum resilience

The combination has been developed to complement VERSUM as well as SPIROCORE strings.


VERSUM SOLO A + D strings offer more presence for both bright and dark instruments.







With the VERSUM SOLO A comes a new freedom of expression! It impresses with its richly smooth, saturated warm tone colors and soloistic brilliance. Even in full performance it does not compromise in sound, both in the delicate Pianissimo as well as the rich Fortissimo and still offers the diverse tonal palette a cellist needs on stage. Thanks to its effortless and elegant response VERSUM SOLO is swift to react. With a beautiful body and distinguished projection, the VERSUM SOLO A is A league of its own!


The new VERSUM SOLO D compensates for the common flaws of D-strings and offers the captivating presence, textured body and vast color spectrum you have been searching for. Its exceptional design made of ultra-light aluminum and a synthetic coated copper winding allows for a much smaller string diameter than commonly expected from a D-string. The result: a brilliant, powerful and rich sound that turns the D-string into an ideal bridge between G and A. It also enables you to easily draw harmonic overtones from your instrument. After a short settling time VERSUM SOLO lets you express elegant piano nuances and lets you live your soloistic presence to the fullest.

VERSUM SOLO A+D cello strings are an unsurpassed game-changer. Not only do they possess the power to ‘cut through’ any acoustical situation, they also allow the listener to hear the glory of the instrument – not just the string.

They enable both instrument and player to shine through the colorful prism of VERSUM SOLO strings, furthering the stimulation of the artist’s imagination to reach greater heights of creativity. They feel wonderful and flexible under the hand and blend beautifully with SPIROCORE tungsten G+C strings and equally well with VERSUM G+C. I recommend them very highly.

They are my absolute favorite strings in the world.
