Open G tuning sounds a G major chord when strummed open. Widely utilized in slide guitar, blues, and folk, it was famously popularized by Keith Richards of the Rolling Stones and early delta blues musicians.
A needle answers "what is the average pitch right now?" A multi-harmonic strobe adds an extra layer to the tuning visualization by showing several harmonics at once, so you can fine-tune more confidently to fractions of a cent.
