Tone character
Fender Original 150s use pure nickel wrap for a warmer, softer voice than modern Nickel-Plated Steel (Bullets). This reconstructs the pre-1970s Fender tone — less bite, more warmth, rounded attack that flatters vintage-voiced single-coils. The 9-42 gauge combined with pure nickel creates one of the softest-playing Fender-branded sets available.
