Ernie Ball has cracked the code with their Slinky Flatwound Bass Strings, creating the first flatwound strings that genuinely feel flat whilst sounding like roundwounds. These innovative strings merge the silky smooth playability that flatwound enthusiasts love with the punchy power that typically comes from roundwound construction.
The secret lies in Ernie Ball's SuperBright Cobalt ribbon wrap technology, combined with Cobalt underwraps that provide exceptional tonal clarity and output. The carefully engineered hex-core to wrap ratio ensures optimal string tension and response across all four strings.
Available in a versatile .040, .060, .070, .095 gauge set, these strings suit players who want the comfortable feel of traditional flats without sacrificing the brightness and punch needed for modern bass playing. The Cobalt construction adds extra presence and definition to your low-end tone.
