i kinda liked your guitar tone....but erm....is it just me or are you playing a different key from the backing track? some parts it fits but some parts it seems a little like not in the same key...
cheers
Hmm for a start, do you know scale patterns? Know a couple of them (just start with 2-3 patterns first) and u can apply them to any key, all over the fretboard. Online sources can be found everywhere. It's always good to know the basic "rules" of improvising, before breaking them.
