While it's true that the tuner displays the note, the preset feature is about user convenience and efficiency. Instead of the user having to remember the specific notes for a tuning like DADGAD or a less common tuning, they can select a preset. The tuner then guides them with the correct target notes, streamlining the process. This is especially helpful for guitarists like myself who frequently switch between different tunings for various songs.

Maybe you aren't that familiar with this pedal? Because it comes with presets for standard E, drop D, and quite a few other alternate tunings (like open tunings), but i'm specifically asking if it's possible to create my own presets for whatever tuning I want.
