Thomastik-Infeld EB344 Powerbass Electric Bass Strings

Thomastik-Infeld makes EB344 strings with a high-carbon steel core wrapped in nickel-plated steel. The result: clearer sound with higher output!

The first time you put on a set of these bass strings, you might have to turn down your amp. That's because Powerbass strings actually deliver a hotter signal (with a higher S/N or signal-to-noise ratio) than the strings you're used to. The reason is in the windings.

Most bass strings have an outer winding of nickel or stainless steel wrapped over a steel core. Since most nickel and stainless formulations aren't magnetically reactive, your magnetic pickup only senses the motion of the string's core. But Powerbass strings are different. Thomastik-Infeld start with an ultra-flexible, high-carbon steel core and then wind them with nickel-plated steel.

This added steel makes the windings magnetically reactive, adding gain at the pickups. Power bass strings are also an ideal solution for players who use a long signal path or whose signal must travel through several effects. Or, just use them to "clean up" your sound. Due to their higher S/N, they produce a cleaner signal in every playing situation.

Powerbass strings deliver modern tone with a balanced spread across the frequency spectrum. They communicate a full, well-rounded bass, throaty mids and solid treble without brittleness and the nickel plated to the windings provides warmth to the tone. Sure, it costs more to put this much engineering into bass strings. But for bassists seeking great tone with an improved signal-to-noise ratio, there's no better investment.

There is a big difference, at least among bass strings, when it comes to design and manufacture. You may be thinking these are out of your price range. However, they're really not if you consider how good they sound and how long they last. I've had them on my bass for two years and I still don't feel the need to change them. They sound as good now as they did on day one. They stay in tune and resist oxidation like no other string. I would have changed 3 or 4 times by now if they were Ernie Balls or Dunlop. They have a sound that is similar to stainless steel- pretty bright and powerful, but capable of very nuanced dynamics like nickel or chrome. They are very much an "everything" string. They also feel a bit like stainless steel, but they are not exceedingly rough. Just a bit more teeth on them than most nickel plated steel strings. Plus they are a neat color, so you can tell something is up with their construction. Infeld is the largest string manufacturer for bowed strings, and their attention to detail certainly carries over into these electrics. $70 seems like a lot, but you get much better string than any of the competition and they last 4 times as long. You spend money on your bass, pickup, signal path, amp, cabinet, and speakers, why not the most important thing, the strings? $70 is like a night out drinking these days. Stay home, practice, and spend the money on something that will make you sound good for 2+ years.
