Every electric string has a steel core, which is what the pickup mostly senses. The outer wrap still matters: it affects how the string vibrates, how much high-end it produces and how strongly it interacts with the pickup's magnetic field.
How the S.I.T. electric range compares:
- Power Wound Nickel: nickel-plated steel wrap. The balanced middle, with clear highs and solid lows.
- Power Steel Stainless: stainless wrap. Brighter, more attack and presence.
- Power Groove Pure Nickel: pure nickel wrap. Warmer and smoother, with a vintage character.
- Power Flat: flatwound. The warmest and smoothest, with very little brightness.
Matching strings to pickups:
- Bright single coils often pair well with nickel-plated or pure nickel to keep the top end sweet.
- Dark or high-output humbuckers can benefit from stainless for extra clarity.
- Jazz and vintage tones suit flatwounds or pure nickel.
Gauge matters too: heavier strings move more metal over the pickup and generally sound fuller. After switching materials or gauges, you may want to adjust pickup height to rebalance the strings.
