Thomastik-Infeld Power-Brights Regular Bottom Electric Guitar Strings

Made in Vienna, Austria, Power-Brights electric guitar strings live up to their name -- delivering hot output with boosted highs to enhance your harmonics.

Thomastik-Infeld Power-Brights love distortion! Round wound Magnecore alloy on a flexible hexcore gives you a bright aggressive tone, extra long sustain and reduced playing effort. Designed to enhance harmonics and percussive effects like tapping, these strings deliver high output plus a boost in the high frequencies to drive effects to the limits.

Rather than create "all-purpose" strings for every playing situation, Thomastik-Infeld focus on making specialized strings to fill specific needs. For electric guitarists, that means Power-Brights. Power-Brights are precisely what their name implies. They deliver a bright, cutting tone -- and they measurably produce more power than other strings. How? Because of their proprietary Magnecore winding technology.

Most guitars utilize nickel or stainless steel windings over a steel core. Since only the core is magnetically reactive, their windings make no contribution to the signal at the pickups. But Magnecore windings are made of high-carbon steel, then plated with nickel. It's a costly process but it yields a string with a measurably higher gain output at the pickup. And higher gain means a better signal-to-noise ratio. Power-Brights are also perfect for heavy effects users or for long signal paths where dropoff could be a problem. Treat yourself to the finest, longest lasting, and most musical strings that precision engineering can produce.

Could not get the bridge knot on the High E to hold. Every time, the string stretched and pulled through the knot, reducing the diameter. I don't recommend.
