I've been playing guitar for a while, and I've only started with power chords back in March of this year. I've been loving playing along with songs that I like for the past 2 weeks (I've mostly focused on practicing certain techniques without playing, so I'm implementing more playing time now). I've been playing Dammit by blink-182 and I've slowed it down in my DAW to about 40BPM. For some reason, I choke when it comes to palm muting after the intro to the first verse, and I seem to have an issue where there's a noticeable gap in between shifting up from the C power chord to the G power chord, unlike the record. What can I do to make that shift sound more smooth? Should I slow the song down even more than that? What could I be doing better?
