Hi folks.
I just read on
Pirastro's website that Obligato bass strings are now available in fifth tuning:
Double Bass Obligato for tuning in fifths
There is an ever growing group of bassists who is interested playing in fifths so that we have decided to offer our successful Obligato line for tuning in fifths.
In cooperation with renowned bassists we have developed this new set of strings, based on the construction and material of our Obligato line. This string set has a powerful and brilliant sound and an excellent harmony across the strings C-G-D-A. The core material of the A-D-G strings has been co-developed with our supplier and we obtain it exclusively. It has the advantage of offering a powerful and wide range of sounds and is unaffected by changes of temperature and humidity.
We have developed a special rope core for the low C string which gives the string a powerful and brilliant tone with a wide range of sounds. The harmony and playability of the set is outstanding.
