Which brings me to the topic I wanted to discuss: I don't think sweep picking really has anything to do with 'complex brain timing' and other stuff I've heard and read.
But, which brings me to why we're opposites when it comes to this, I hit sweeps involving all fingers pretty clean. Unfortunately I'm not even sure what I'm doing in particular to mute all of them correctly being that my first try seemed to do it. I use my palm for raking down and fingers for raking up, on and off to mute them.. if that makes sense.
But the downside of this project, although I'm hitting them clean, and occasionally kinda fast, i'm hitting a combination of patterns that resemble pentatonic scales, power chords, and random notes. Totally experimental, and only a few out of the many repetitive patterns I've come up with sound decent.
I know zero arpeggios. I really don't... lol. Seems kind of absurd, but my entire, very dedicated, time with guitar has been spent towards .... So in a lot of ways, I am a COMPLETE guitar newb...
