DIY work can be genuinely satisfying, yet it turns risky the moment "confidence" replaces verification. A guitar is a tensioned system built on small tolerances, so minor errors can cascade into fret buzz, tuning drift, cosmetic scarring, or stripped hardware that never quite tightens again. The goal isn't speed, it's controlled adjustment with a clear record of what changed and why. The right equipment not only makes tasks easier, but it also limits the damage you can do while learning.
