Although the frets are smaller, the distances closer yet - and in spite of the different mood (equivalent of the guitar with Capo on 5th fret) - the small Guitalele plays almost like a guitar. They might also agree as a guitar with Children guitar strings. I did not do it, I liked the sound better.
The build quality is surprisingly good and sound, the sound sounds like Ukulele - cute.
Conclusion: The Guitalele is ideally suited to provide them with to take on the journey, to play on the sofa or something to accompany songs - here is not very voluminous sound is an advantage because the voice is not drowned out.
Ambitious guitarist can get out decent, you can see that on various Internet video well.
The Guitalele is uneingeschrnkt recommended eg as a second or third instrument besides a normal guitar.
