TONICA strings have a core made from nylon.
 
- They produce a lively well-rounded sound, perfectly balanced across all four strings.
- With substantially reduced background 'hiss', players can sustain a more even tone helping to achieve smoother string crossings.
- Very easy response.
- Good projection and brilliance with warm sound.
- Due to their medium tension Tonica strings are suitable for all instruments.
- Insensitive to variations in temperature and humidity.
