StewMac

StewMac is the world's leading company and YouTube channel for guitar lutherie, setup and repair. Their videos — presented mainly by Dan Erlewine, one of the most respected luthiers in the world — are a continuous masterclass in the care and improvement of stringed instruments.

The channel's content ranges from basic action and intonation adjustments to complex repairs of bodies, necks and electronics. Each video is presented with exceptional clarity, using the tools and materials that StewMac itself sells, creating a coherent ecosystem between the shop and the educational channel.

For any guitarist who wants to understand their instrument beyond playing it — and be able to maintain, adjust and repair it — the StewMac channel is indispensable. Their videos have democratised luthier knowledge in a way that was previously inaccessible to most people.
