Yeah, that's a pretty good string stabber.
I'm sure you are familiar with the "Flamenco" style multi finger downward flourish (where you kind of roll your hand/fingers downward to rake the nails across a chord). This stabbing is just a tighter and targeted attack.
One thing my old bass buddy used to do (and he stole it from Entwhistle) is a hyper rapid flicking back and forth of the finger to essentially speed pick a bass string (or two at a time). Pretty cool but doesn't work that great on guit without some ultra control (strings are too close together).
Unfortunately I've never really had the time or opportunity to really getting my finger picking technique down to real pro levels. I can perform most of the techniques well but cannot sustain them long enough with enough clarity to really muscle through pieces like you probably can.
Like I can do basic classical pieces or finger plucked tunes but super fast runs or crazy arpeggios elude me. I'd just need to practice it all I guess but playing causes me such enormous pain these days and I have mountains of plectrum material to track that I just stick to what I know.
There is something entirely satisfying about flesh and nail though. I love noodling around on my bass and guits with my fingers. It just turns into too much moosh on a track though.
I do however do quite a bit of hybrid picking (using the definition of plectrum plus finger picking... seems that term gets used for other styles). I'm actually tracking some bluesy stuff using that method right now and let my nails grow a bit to do so. Pretty simplistic stuff (just plectrum and middle finger) but effective.
Cheers.
PS: Yeah... totes post sumthin'. I'd be interested.
