Many of my students get their first start on the acoustic guitar. This is a cost-effective way to begin lessons since all that is needed is a reasonably priced instrument, a case or gig-bag, and a few supplies.
Choosing the right sized instrument makes learning much easier. Student’s who are learning guitar between the ages of 7-9 have better success starting with a 1/2 sized acoustic guitar. Students between 9 – 10 usually do best with a 3/4 sized guitar. A full-sized guitar will be a good fit for students ages 11 – adult. Most of my students will learn on a regular right-hand oriented instrument even if they are left-handed. It’s also perfectly fine to choose a left-handed guitar if that feels intuitively better.
