Martin Authentic Acoustic SP Bass Strings .045 – .105

We’ve got your rhythm section covered with Martin Authentic Acoustic SP® Bass strings. We start with our highest tensile-strength core wire, then tin-plate it on all six strings for added corrosion resistance; because what you don’t see matters! Available in long-lasting 92/8 Phosphor Bronze.

Martin Authentic Acoustic Bass strings offer excellent tuning stability, corrosion resistance, and great playability.
