I like the garage rock style and the style of the who and Beatles but want to know what methods they use such as the chords and progression they used and how to come up with my own, now some of the things they used I might know but may you please give me the basic steps to that garage rock rhythm guitar style

Step one - learn their riffs. It's really just hard purposefully sloppy playing. You need to be aggressive with the strumming hand and use good dampening with the left.

Step two - take the skills you learnt in step 1 and apply them to your own progression.

reverb66 thanks, you couldn't have made it any easier so with that said I'm going to learn some simple songs for starters then move my way up to more stuff
