LaBella Black Tapes are less-bright than the newly-developed White Tapes. They have a wonderful feel-- so friendly on the fingers!
Although they are "Heavy" guage, or "High Tension", they don't really feel like it. If you play Plectrum-style Jazz or Fingerstyle, you will probably love 'em. If you are trying to max-out the volume of your Jazz Box, these strings are probably NOT for you.
There are two camps out there-- those who love these strings, and those who really hate 'em. Another not-much-talked-about aspect of these strings is their lack of sustain, which makes for GREAT rhythm playing-- i.e. shorter quarter notes. If you are plugging in and playing rhythm on a big band, the amped sound doesn't get too electric if you've paid attention to your rig. Electric Archtop rhythm guitar can get unruly because the notes elongate and it sounds bad... if you play rhythm you probably know what I mean.
They don't feel AT ALL like a typical roundwound OR flatwound, for that matter. A very unique approach to string design that puts them one step toward a Classical Guitar-type feel.
The feel of these strings is very addictive, so look out!
If you are clocking in lots of time on the instrument, these strings can really be a boon, in terms of comfort.
It will be prefect if this set's thickest string is also flat-wound.
So far this set is the thickest flat wound 7 string I could find. I only use the 1 to 6th (EADGBE) strings as the 2nd to 7th strings on my custom fretless 8 string electric guitar, but add a .010 and a chrome flat wound .080 as the 1st and 8th strings. Finally I have a prefect set of 8 strings.
