Most "free" guitar tools online bury you in ads, pop-ups or a sign-up wall. These don't — they run entirely in your browser, nothing is uploaded, and there's no account. They pair naturally with GuitarToneAdapt: tune up with the tuner, lock your timing with the metronome, work out the chords and capo, then dial in the actual tone of the song on your own rig. All free.
