I received the newest version of the S.I.T. C#0 string about a week ago , a .195 if I remember correctly. I put it on the Adler 11 string and played it through an Ampeg svt pro 4 (correct name ?) into my new Basson b510 sub contra cabinet. The string is most definitely audible now. You can clearly hear the open C#, 1st fret D , the Eb and the E. The b510 sc was specifically designed to handle the 11 string and other full range guitars and keyboards.It's 1400 watts @8ohms. I might have thought I heard the notes on the old C# string ,but along with myself ,two other qualified listeners heard every note played on the new string as "clear as a bell" . There is a nice even balance when playing across the B, F# and C# string. I also played through the Basson prototype B310 and although it didn't shake the ground ,the string was clearly audible. The new string doesn't "flop around" and is now thicker where it makes contact with the bridge saddle. In my opinion ,Jauqo III-X and S.I.T. have made a huge contribution to the bass guitar.
