Good, well balanced flatwound strings
Review by Nelson T. on 13 Jan 2017 review stating Good, well balanced flatwound strings Caveat: I did not buy these strings via StringsByMail, but thought I'd give a review of this set of strings, since not too many places in North America sell Optima strings to begin with.
Yes, they're pricey. Are they worth it? In my opinion, yes they are.
They are zingy at first, almost annoyingly so (a lot of flatwounds are like that before they are broken in), but the E string already sounds fairly deep. After a couple of weeks' worth of playing, the zing goes away, and you are left with some versatile strings that can sound modern and vintage (especially when you foam mute them at the bridge).
Compared to other flatwounds, they have a very well-defined click in their top end, which help with cutting through. They sound slightly more scooped, and have almost a woody tone, especially when played with fingers. They are supple, and don't seem to be particularly stiff compared to some other flatwounds you could buy on here.
Compared to the more old school flats like Labellas and GHS, they are not quite as punchy or thumpy, although they will definitely give plenty of both. From out of the package, this set is probably the most tonally consistent string to string I have ever used -- something that is difficult to claim with other fresh new flatwounds before they break in.
The orange silks are dense and can take handling fine. If you want to hear them on a cheapo P-bass by a (very) amateur player, look on youtube under the username nerkoids, I have a couple of videos that demonstrate them.
