A 5-string long-scale bass set extending EXL165’s range from 45 up to a 0.135? low B. Constructed with high-carbon steel cores and nickel-plated steel wrap, these strings produce tight, articulate low B response with the same clear mids and highs as the 4-string set. The hybrid gauge yields balanced tension – tight lows for punchy bottom end, lighter top strings for smooth playability – ideal for fingerstyle or pick. Uncoated for a natural feel, D’Addario’s precision winding provides stable tuning and exceptional longevity, so your extended-range bass cuts through the mix with confidence and clarity.
