What is the best way to set up your ukulele?

To set up your Ukulele for optimal playability, start by ensuring it's properly tuned to G-C-E-A. Check the action by measuring string height at the nut and saddle; adjust as needed for comfort. Ensure the neck is straight and free of any warping, and consider changing old strings for better tone and playability. Lastly, clean the fretboard and body to maintain the instrument's condition and sound quality.
