Tuning your guitar, ukulele, mandoline, or bass is integrated into all the fretboards when you are making tabs!
Step One: If you HOVER over the fretboard, the tooltip will appear telling you to "Click to Tune Guitar":
Step Two: To play the note that the string is tuned to, all you need to do is click on the note corresponding to the string on the left side of the fretboard. Once you click, there will be a delay, and then a midi sound will play twice. Make sure you have your sound on!
Step Three: We've added a little delay of five seconds so you have time to get ready.
This works on all instruments that you can choose in guitar tab creator, as well as any of the custom tunings!
