Well I've been going through intense speeding/accuracy training doing riffs and scales over and over again (I've got no problem with repeatition, doesn't bore me).

But say for example I got one scale down and I can shred it, will that mean that... I can only shred that scale but nothing else? Or will be able to shred other things as well we little practise of course?

Mainly because I can't practise a lot of different stuff, and concentrating on few things, I hope this will help with my guitar playing overall.
