Innovation Double Bass Strings have a unique, non-metallic core which provide a gut-like tone without the cost or maintenance of gut upright bass strings. They hold their pitch well in climate and temperature changes, and most of their strings are equally suited for pizzicato (plucking) and arco (bowing).

Many of Innovation's strings are similar in design, but they assign different names to the different tensions/gauges. For instance, if you like the description of these strings but prefer a lighter feel, the "Rockabilly" set is essentially the "Ultra Black Light." You don't have to play Rockabilly to enjoy them, either!

Innovation UB (Ultra-Black) Double Bass Strings are named for their distinctive "Ultra Black" colored outer winding, and work well for a player seeking a fuller, darker-sounding string for traditional jazz and other styles. They are constructed using a flexible braided core with a black tape winding. Unlike most other "black" strings, they can be bowed successfully. UltraBlack strings have a darker tone, like most gut strings, but have the advantage of being a bit more distinct than gut. They offer a less "twangy" alternative to other popular jazz strings. The flexibility of the core (a nylon wound in a "rope" pattern) allows you to really "dig in" without having the string excessively modulate out of tune. Yet the outer wrapping has a hard enough surface to get a nice "growl" or "mwah" from fingerboard interaction. Despite it being marketed as a "Jazz" string for pizz players, the surface of the string reportedly is also equally bow-friendly.

The UltraBlacks fill the void between the traditional gut string sound and more modern steel strings; they have a solid fundamental and middling sustain. Players thereby find them appropriate for nearly all pizzicato work, whether it be jazz, bluegrass, folk, or traditional music.

Note: All of the Innovation strings do not contain any ferrous materials; they are not suitable for use with a magnetic pickup, like the Schaller we carry. They will work with all typical piezo-based pickups (like the Realist, Full Circle, and all the K&K pickups and systems).

Innovation designs these 3/4 size bass strings to fit on a standard 3/4 size bass. They may very well fit your bass if it is larger than 3/4. For your reference, the lengths of the string, as measured against the bass tailpiece to the nut is 51.5 inches, plus an additional 17 inches to handle stringing in the headstock.
