I think all guitarist should buy a ukulele because if you can play guitar you can quickly and easily transfer your skills to strumming the ukulele.
The ukulele will put smile on anyones face. It’s instant fun and easy to take anywhere.
I bought my first soprano ukulele (it was a cheap blue moon model) to take away on holiday as I didn’t have the space for a guitar.
I was hooked on the little thing. I then invested in a Kala tenor uke.
Songs I haven’t used for years take on new life with the ukulele.
