What Size Guitar Is 

Best for Your Child?

Created by a Guitar Teacher & Dad

I designed these beginner bundles from 35+ years of real guitar experience

I’m Adrian Curran from Warrenpoint, Co. Down, Ireland — a guitarist, teacher, and parent who’s helped hundreds of students start their musical journey.

When my own kids wanted to play guitar, I realised most options were either oversized toys or confusing adult gear. So I built the bundle I wish we’d had — fun, frustration-free, and ready to play straight out of the box.

These are the same lessons and tools I use with my students every day, designed to build confidence and spark joy — even if you’ve never played a note before.
