Tuner
The Tuner effect can be used to tune instruments like guitar, bass etc.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.
Offsets can be specified for non-chromatic tunings.
Tip: The Tuner typically works best if it's used before any other effects (like the Guitar Amp).
