Some of the best beginner classical guitars come fitted with a pickup, which means you can plug it into an amp or PA system. So, if you’re thinking that you want to work up to playing gigs or open-mic nights, without having to upgrade your guitar before you do, then consider a model with a built-in pickup. If you’re fairly confident that you don’t need this, and just want to play at home, or take lessons/exams, then you will get plenty of volume without needing a pickup or amp.
