Optima Unique Studio Gold Electric Bass Strings Super Long 45-105

Gives you a tone color somewhere between steel and nickel, with punchy attack and impressive sustain, with good character overtones in the mids; doesn't lose pitch when fretting - I've actually drop-tuned mine a lot and they still sound good! Their tuning sets fast and above all else I love the fact that the gold layer means I'm not being exposed to microplastics, nickel or heavy metal impurities!
