To enter the onboard tuner on the Spark GO, simply power on the Spark GO and hold the PRESET button on the top panel.
The four preset LEDs will all blink 2 times when entering the tuner mode. While in tuner mode, the 4 Preset LEDs will measure the note being played.
*The Spark GO will be muted when entering the tuner mode.
To exit tuner mode, press the PRESET button again or the POWER button (on the side panel).
The onboard tuner is a chromatic tuner. If you're unsure whether your instrument is noticeably out of tune, we suggest connecting the Spark GO to the Spark app (Tone Control) to check the note when tuning accurately.
You can also enter the tuner mode within the Spark app (Menu -> Tuner).
