Members · train the tuner

Pluck each string one at a time while the tuner is running. Your samples stay on your device and sharpen detection for your guitar's tone.

Tip: get quiet, pluck firmly, let the note ring. Works best on a laptop with the guitar held near the mic. Tuner runs entirely in your browser. The audio never leaves your device.

The tuner is a Pro feature while in beta.
