Features
Tonica strings have a core made from nylon.
They produce a lively well-rounded sound, perfectly balanced across all four strings.
Responding instantly to any bowing style, they reward both player and listener with an open and direct sound.
With substantially reduced background 'hiss', players can sustain a more even tone helping to achieve smoother string crossings.
With a highly responsive left hand feel, Tonica strings remain very easy to play all the way up to the highest positions.
Projection and brilliance have been upgraded.
However, this excess does not mean that the Tonica has lost its warmth.
Playing pianissimo has considerably improved.
All bow strokes are possible resulting in smooth crossings from one note to another.
Easy right hand articulation and tone attack.
Due to their medium string tension Tonica strings are suitable for all instruments. Insensitive to variations in temperature and humidity
Variations
E-steel wound with aluminum – warmer sound
