Tuner

The Tuner effect can be used to tune instruments like guitar, bass etc.

The Tuner typically works best if it's used before any other effects (like the Guitar Amp).

The A box determines the frequency of note A5. The Tuner effect can be used to measure the frequency of an A5 played on, for example, a piano. This value can be entered in the A box, so other instruments can be tuned to the same pitch.
