So do you have to rosin your pick to get the requisite friction? I can see it working on the wound strings a lot more than the unwound otherwise as there wouldn't be enough movement I would think.
I would like to see your approach here though, unique as it sounds.
I'm not really interested in whether or not he can actually play at 1300bpm personally.
I'm more interested in this technique he claims to be using.
The only thing I can think of is some picking technique where you pull the pick up and away from the string rather than across it letting the rosin on the pick "activate" it.
I have some rosin, so I can test that hypothesis pretty easily.
It seems unlikely though, and until/unless he's nice enough to upload a video demonstrating the technique in detail I'm going with a combination of economy picking, legato and a shitload of distortion.
OP if you do upload a video of the technique, do it on the clean channel.
