In Malmsteen's website, he said he could play faster if he wanted to, but hes happy with how fast he is right now. Kinda hard to belive though, you know with the BIG EGO of him.

Yes, I do belive there is a platue of speed. You muscles can only go a certain speed and then they max out.

And, one reason is, if guitarist could go faster, they wouldnt. Too much speed sounds very muffled up. Kinda like Marcus Paus. He has so much speed that doesnt even sound like guitar. It doenst even sound like hes trying to play anything, just random notes.

thats my opinion...
