I disagree,
I tried learning the guitar and struggled, being a musically untalented duffer, I got a Uk, and now am looking forward to trying the guitar again, It can only of helped, it is easier to play, but alot of the chords are the same, so a very good grounding.
BTW Israel Kam’s version of somewhere over the rainbow is v hard to master, that is the goal! Many a guitar player would fail at it.

Im currently sat (for 2 weeks work reasons) by Finale Liguria in Italy, with the enduro course in site, and no bike, learning Billie Jean, Ukelele version! It helps ease the pain of being here and having no bike!
Have fun.
