Gauge depends mostly on your tuning. Many players are comfortable with standard gauges in standard tuning or Drop D, while lower tunings often benefit from heavier strings like .050–.110 or more to keep a firm feel and note definition. Look for a gauge that feels comfortable and gives you control, not just the heaviest set available.
Flatwounds are less common in metal but can be a great fit for doom and stoner metal, where a warmer, smoother tone is the goal.
S.I.T. options for metal:
- Power Wound Nickel: all-around choice for classic and modern metal
- Foundations Stainless: lower tunings and maximum articulation
- Fusion Wound Stainless: progressive and technical players
- Fusion Wound Nickel: balanced tone across multiple genres
