I just got a Cirrus 4 string and love the construction, truly a well made instrument. I strung it with D'Addario Steels and it is way too zingy. The overtones seem to be off somehow. I am toying with the idea of flats, specifically TI for the tension, but wondered if anyone on TB has had experience with flats on a Cirrus. I am open to suggestions as to other flats or other strings.
