Corelli Bass 370 Series bass strings are made of tungsten steel, a very strong, supple, lightweight material known for its high tensile strength in very narrow gauges. The 370 Series come in three gauges:
· 370 Medium is the lightest gauge, and is great for acrobatic solo work, or for very lightly constructed instruments which are overstressed by heavier strings. 370 Medium bass strings are also available in fractional sizes. In orchestra tuning G-D-A-E.
· 370 Forte is the middle tension string and
· 370 ForteTX is the higher tension string. Both are an excellent choice for bass players wanting a hybrid use string.
