For the two techniques I mentioned before - you won't need to use the fleshy part of your picking hand thumb. You see, that is what's called a pinch harmonic. The harmonics I spkoe of are actually the same as a pinch harmonic except you use one of your other fingers to actually sound the node/harmonic.

I take o few pics tonight and post them somewhere so you can see me doing the techniques. I must say that these harmonics are very unorthodox and, it's a different way to go about doing the same thing. But, keep in mind it will expand your physical abilities a little bit. I'll get back to this post soon!
