Independent shopping perspective
Markbass Energy Series strings pair a 30–130 medium gauge with selected alloy steel wire wound around a hexagonal, high-carbon-content core. Their calibrated diameter and tension are designed to give a consistent playing feel, while corrosion resistance supports ongoing use. Expect the series’ bright character to sit alongside rich harmonics and a deep, fat low end—useful for players who want a more forward, harmonically detailed bass-string voice.
