Description
When your low B needs to cut through without going dull on you, SIT’s Foundation stainless steel set in a light 5-string gauge is worth swapping in. These aren’t just another round of standard bass strings — SIT built the Foundation line around a new core material specifically to boost touch sensitivity, so every pluck, slap, or pick attack translates immediately into tone instead of getting absorbed by the string itself.
Stainless steel winding gives you that crisp, aggressive brightness that stays audible in a mix, plus the added flexibility that makes fast runs and wide-interval jumps feel less like work. If your basses tend to eat brightness within a few weeks, this set is designed to fight that fade harder than typical strings, keeping the top end alive longer.
Foundation strings are part of SIT’s rebuild of what a bass string should feel like under the fingers — responsive, flexible, and tuned for players who notice the difference between a string that’s merely holding pitch and one that’s actually pushing tone forward.
- Light gauge, 5-string set
- Stainless steel construction for bright, cutting tone
- New-generation core for enhanced touch response
- Extra flexibility for easier playability
- Also available in nickel, and in 4 and 6-string configurations
Stock up now — because a bass string only sounds this alive for so long, and StringRush makes it easy to always have a fresh set on deck.
