Yesterday I put on my first full set of Spirocore Starks, replacing my mix of Mittels/Oliv G. Don't know why I didn't do this before. The sound of the Starks is bigger than any string I've ever played. So why didn't I try them before now? I have to admit I was afraid to.
Going back a few years I've played Spiro Weichs, Belcantos, Evahs. Then came the Spiro Mittel E into the mix, leading finally to the EAD Mittels as a whole set at first and then adding in the Oliv G. And there it was for the last seven years or so. The Mittels sounded better and better, loud, growly, good deep clear tone, pizz and arco. Actually the Mittels initially took some getting used to, but the sound was bigger than the strings I had tried before. At some point two or three years ago, I strung up a Stark E with the Mittels and Oliv G. I loved that Stark E, but took it off and put on the Mittel E when changing last. I was a bit concerned the Oliv G wouldn't keep the balance with the Stark E. So now it seems like the inevitable has just happened: Full set of Starks is on.
I agree with the description of the Starks in the OP of this thread. Huge, clearly defined fundamental. It feels absolutely earthshakingly beautiful. These strings do not crap out when you dig in, they give back as much volume as you want them to. The upper register sings beautifully and louder than even the Mittels. Just now starting out with the Starks, they feel under the fingers like the difference I felt when playing the Mittels for the first time after Weichs, only moreso.
So why didn't I try a full set of Starks before? I was worried that the greater tension of the Starks would damage my bass. I read the threads where TBers talk about that (usually someone who hasn't tried Starks). I've been rethinking that concern and am pretty sure my bass can withstand the Starks' higher tension. The bass is a 1993 Horst Gruenert (Bavaria), a sturdy carved 3/4 with a top that is certainly not thin or fragile. It has been set up with a perfectly fitted sound post, strong bass bar, and was made with an extended saddle to reduce the bridge angle and string tension. I suppose the extended saddle is a clue that the bass was made to withstand high tension strings.
My mensur is 105 cm, and the strings I bought are Orchestra "S36ST-S39ST heavy". I don't think these are 4/4 size, the light green wrap has contact with all four tuning pegs, but there is no size indication on the package.
But the real shocker is how the Starks bring out the best sound I have ever heard coming out of my bass. On this bass the Weichs or Evahs never produced a huge sound, no matter how hard I played. Mittels gave this bass a bigger sound, and I guess after finding that out I realized the bass needs more tension. Now the sound is just huge.
Bottom line is with the Starks the sound is just bigger, deeper, clearer than I imagined it could be. It is like this bass was made for Starks, it just took me quite a few years to realize that. It would be interesting to know how many bassists avoid Starks because of fear of damaging their bass, and also how many basses have actually been damaged by Starks.
