Though Sonores will remain an ongoing inventive and research-based model, the Tempera String itself is more like a full-stop at the end of sentence. In other words, Sonores will continue as usual: Develop new models, respond to specific requests (eg. special tunings) and always come up with something new, pushing the boundaries further. Tempera, on the other hand, will be consistent, offering a more reduced palette of string models swiftly and reliably.

While retaining the well known ‘Genssler String’ sound, the Tempera Design took players of steel strings into consideration right from the beginning. Uncompromising in terms of sound, they significantly facilitate the transition away from steel strings. To achieve that, we invented the patented Tempera Technology and changed the construction of the core which results in more resistance against bow weight and an extremely focussed and deep sound.

Special requests are usually a case for the Sonores workshop, where (almost) anything can be realized.

Nevertheless, you are welcome to contact us and we can decide on a case-by-case basis whether your request can also be realized with the Tempera technology.

A lot could be written about this question, because it touches on big areas like string sound, acoustics and finally artistic issues.

In our opinion, today's trend of making double bass strings with over 30kg tension is absolutely not ideal, because the instrument's ability to vibrate is reduced and instead an unfree, compressed sound is produced.

We should also not ignore the fact that the conception of today's instruments comes from a time when playing was done on gut strings with about 18kg per string. So the question is really, what is the "normal" tension for a string?

The Tempera Strings are currently available only as an arco-optimized version. A more pizz-friendly model is in developement but it might take a while to be released. You can sign up for the news letter or preorder. Or, if you are in a hurry, you can choose a pizz oriented model from the Sonores Workshop (www.sonores-strings.de

Our strings have a very long life span when treated well and mounted correctly. Please check out our instructions here.

The strings are designed to sound ideal not just in the first weeks, but AFTER the first weeks. Bear in mind that both new strings and the instrument itself need a few days to mature and acquire the desired sound.

Alcohol is best for cleaning.

We do ship to (nearly) any country in the world. In some cases though, it might be easier to contact one of our partners in your area.

Shipping costs are borne by the buyer and depend on the destination country. For exact shipping cost to you, please feel free to contact us.

We currently don't give a warranty on the Tempera strings.

Due to the significantly complex production process, we don't give away strings for free. If you are interested in testing out our strings, you can either visit us in Berlin or one of our partners.

The tailpiece is a very influential part of the instrument. We recommend heavy tailpieces in combination with our strings. The best results we received with the Sonores tailpiece (www.sonores-strings.de).
However, when switching from conventional strings to Tempera or Sonores strings, we recommend first leaving the original setup for a few weeks to settle. After that it is in most cases a gain in sound volume and depth to change the tailpiece.
