I have always been an alternate picker and an unconscious 2-way pick slanter.
I purchased the Paul Gilbert, Vinnie Moore and Michael Angelo’s StarLicks videos when they came out, which was the basis for a lot of my practice schedule; exercises and a lot of metronome work. Eventually I was doing reviews of this videos so I have all of them
I remember noticing Paul Gilbert’s pick slanting and experimenting with downward pick slanting; thinking that it may be important, not realising that I was already a 2 way pick slanter and how important it really was. I had none of the insight Troy did, just that it was a thing.
When Troy’s Cracking the Code came out it was a lightning bolt and made perfect sense to me.
So I find it very bemusing when players dismiss Troy’s seminal work on the topic, their loss I guess.
Anyone else have any picking slanting intuition prior to Troy’s definitive study of the topic?
