I got this a while back and it's quite useful. For most of the scales, Troy shows you 3-note-per-string variants and he also gives quick tips on where to use certain modal scales.
I'd recommend this book to anyone.
Where did you find this book? I can't find this one on Kalahari? The only similar sort of description I can find is "Learn Rock Lead guitar" or something like that.
I'm starting to go into more lead \ riff type stuff and need as much info and lessons as possible :-[
I think I got it from my friend (and dormant forum member 😛) Allyson @ Specialized Music . co . za.
They're in Rivonia but I'm not sure if they sell direct to the public. If not, ask them for a shop they can recommend.
