On my
old Tirol Bass I have a set of Helicore Orchestra/Solo gauge tuned to regular pitch. These Bow and Pizz great. The Bass was in need of a lighter tensioned string before I ever owned it and one Luthier suggested these and put them on about 2 years ago. I just got the Bass a few months ago but so far, so good.
I also took these off for a moment and tried them on my
Attrib. Cornerless Storioni. They were good on that Bass as well. The gauges measure close to the regular Flexocor 92s if that is of any help to know.
Now they are back on the Tyrolean and work just fine for what ever use I need them. Mostly I just use that Bass to practice at home with for Orchestra but I did take it out on a Jazz gig and was quite impressed with it overall. The Bass was fun to play on with those Strings.
