Guitars which have bad action will prevent playing well and cause very sore finger tips on the chording hand.
Solution. Get a Guitar that does not hurt like a Fender or Alvarez etc OR If you really wanna have it easy get a gut strung Guitar till you get used to chording.
Here again is my G chording system for the lazy player who likes to learn fast. BTW These 'shapes' been around since the 60's. I did not invent em.
