Welcome Kallen,
I am pleased you are enjoying learning guitar.
Guitar Tricks is a great site. All the teachers are good.
I have just completed Core Lessons 1 & 2 and I learnt so much from Lisa. Yes she is very good.
The Yamaha Pacifica is a nice guitar and good for beginners.
Take it steady and don't rush. It will pay off in the end.
I wish you well .
Kind regards
Joe
