Yamaha make nice electrics. I still find Tabs a pain in the rear after 12+ years of "doing" them, get someone to show you the riff if possible.Break down bigger riffs into smaller 2/3 note sections then string em together again,


slow down as well - this helps.

You can use advanced playing techniques to make a guitar screech or get feedback by getting to close to the amp (and many other ways- such as effects pedals/boxes).
