I took guitar lessons for a while but I never learned anything because I wasn't taught good exercises and I didn't practice(whoops). Also every class was me and the teacher trying to work through a song so I never learned anything other than how to do the start of Paranoid by Black Sabbath and the start of Wish You Were Here by Pink Floyd (which are all gone and erased from my memory now).
Having watched the funny music anime is making me wanna pick up my dusty sun bleached squier and try to actually practice a little. I already gave up several times before so it's likely I won't get it this time but it's worth a try I guess.
