Digital pedals: presets, display, USB and MIDI

For a digital effect, test the management functions as well as the audio path.

Check:

• loading and changing presets;
• display operation;
• encoders and buttons;
• saving an edit when safe to do so;
• USB, MIDI or Bluetooth if important to your use;
• power supply compatibility;
• any obvious reset or lock issue.

You do not need to test every advanced feature, but you should verify the functions that determine how you will actually use the unit.

If software access or an account is required, clarify before buying which elements depend on the previous owner.
