Yes, it's yet another thread about these strings. I'm currently rehearsing for a Christmas theater show in a few weeks; the material is everything from Sinatra to Bruce Springsteen to Faith Hill to Trans-Siberian Orchestra. It's become apparent that my basses strung with rounds are just a little too abrasive and in your face for some of the material that was originally recorded with double-bass, especially the older jazz and jazz-influenced pop. Truth is, I have always hated flats. I love tapewounds in certain circumstances, but very rarely have I ever heard a bass strung with flats that I really liked, even fretless. There have always been two things I've disliked with most flats I've heard. One, they always sounded super boxy to my ears. And I'm a mid-range lover, but flats always emphasized the ugly mids that we try to scoop out in most instances. Two, they always sounded unfocused and tubby in the low-end. Regardless, I knew I had to put a much more mellow string on one of my basses for some of this Christmas material. I decided to take the plunge on the Thomastiks, since they are so highly praised. While I'd never spend that amount of money on a roundwound string, since flats last years upon years, I could justify the investment for the Thomastiks. I've had them on a Carvin LB75 for about a day so far and dang, I am impressed. They have everything great about flats, such as the clean tone with little fret noise and present but not abrasive highs, and don't have what I have traditionally hated about flats: boxy mids and tubby low-end. The mids can go from smooth to punchy but never boxy or woody. The low-end is big and enveloping, but never unfocused or flubby. I once read someone here say that you don't need a compressor with flats and I understand what that poster meant. All of the strings seem to have perfectly balanced output, from high G to low B. I have a modern country gig tomorrow, so that's a pure roundwound gig. But Christmas rehearsal is on Sunday and I'm pretty excited about trying out the flats there. The modern stuff, like the TOS, Faith Hill, Eagles, etc. will still get the rounds, but the Brenda Lee, Vince Guaraldi, Sinatra, Nat King Cole, etc. will definitely be getting the flats.
