I just got a uke yesterday. I am a veteran guitar player so i learnt ukulele in just a couple of hours. For all those guitarists out there... UKULELE IS VERY SIMPLE! Its a fun and easy instrument that you will be glad you learnt!
Piano and harmonica player here- I was thinking I'd be useless at ukulele but I've been really pleased with how quick it's been to pick up enough to plink and plonk away with little tunes. Got a chart up on my wall with the chords, and I'm good to go!
