the wah wah tone is not bad. the playing, make sure you listen to the original satriani recording to get the rhythm of the melody down. some parts are correct, some parts (ie: the main melody), the rhythm is not accurate. so try listening to the original more, and practise the rhythm of the licks. good try, keep practising and ull get there.
