Spirocore Solo Double Bass 3/4 : Spirocores never lie

Any upright player knows these strings. They are excellent quality, medium to low tension, bright sound and great sustain. The tricky part comes when you have to play arco: depending on the bass and on the setup, many (me included) find the G and the D string a little too bright, especially when the set is brand new. The highest pitches do not sound great with arco on the top Spiros. I'll repeat, of course it always depends on the bass, but I wouldn't recommend to have a G spiro to play Bottesini or Koussevitzky. On the other side, I would never exchange the punch and the power of the A and E strings, even when bowed. Right now my bass is E and A Spiros and D and G Obligatos.

Last but not least: of all the strings I tried, Spirocores are definitely the ones with the longest lifespan.

Conclusion is that if you have to only play jazz with your bass, this set will probably suit you fine. For those who need to play different styles, try them on and find out what do they do for you!
