Even with an inexpensive ukulele, it will improve considerably just by replacing the plastic nut with a cow bone nut. Ukuleles come in various sizes. If it's larger than the one you're replacing, you can just shave it down, but if it's smaller, there's nothing you can do, so please check the size carefully. There is probably no exact same item, so installation requires height adjustment and adjustment of the saddle and nut installation width while checking the string height.
