Overview

Restringing a teaching studio or a busy gigging rig is easier with a bulk box of Martin phosphor bronze strings in light gauge. A tin plated, high tensile core gives quicker response and steadier tuning under bronze wrap wire.

Supply and consistency are the case: the same set every change, stored in packaging made to resist corrosion. Light gauge balances volume and playability for most acoustics. It is a lot of strings for a casual player.

Who it's for

Music schools, repair benches and working players who want a steady supply of one familiar set. Occasional players will not get through the box.

Performance notes

The tin plated core resists corrosion and holds tune as the string stretches in. Phosphor bronze gives a warm, balanced voice. Light gauge offers a middle ground between easy bends and enough tension to drive the top.
