You don’t need an expensive guitar to take guitar lessons for beginners but you should have a good guitar. Make sure it’s well constructed and that it’s been properly setup to produce the finest sound possible. There’s nothing worse for a guitar beginner than to play a note perfectly and having it sound terrible because the guitar is terrible.
Your best bet before you take guitar lessons for beginners is to go to a professional guitar store and ask them to set you up with a nice acoustic (people don’t really learn on an electric). Have them set it up to give you the ideal sound and strum it a little in there to make sure it feels good for you. Don’t be afraid to try different guitars. The beautiful thing is that before long you’ll have learned to play guitar and you’ll be in the store playing, having fun, and getting closer to your dreams of guitar success.
