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

Halfway between the kick drum and the mandolin lies full, thumping bass. 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.
