I started as a complete beginner But adam is an excellent instructor and he fine tuned his lessons to adapt to my skill level and took into account the limited time I had to practice. He gives me great tips on how to practice playing different notes, and gives me increasingly sophisticated finger exercises to help me get used to switching between different chords/notes. Introduced me to different riffs I could use to practice, tune my guitar. And he was also very willing to share the more pedantic details of music.
Adam makes the whole experience really fun and I learn a lot more in those couple of classes weekly than I though I would and was even able to read the notes off of internet and play my favorite song in the end.
I would gladly recommend adam to any one wanting to learn how to play guitar.
