I already practice with scales, but I'm not quite satisfied with how far I've gotten. I was wondering if anyone had some practicing techniques to get my solo/lead playing faster. I'm looking to speed up my sweeps, taps, improvising, and just my finger speed in general. I'll try any ideas.
yeah, i already practice all the scale modes i know in every key i know with a metronome at different speeds spread throughout the day. I'm just trying to see if there are any other ways to practice and gain speed, maybe a little quicker? thanks for the advice, though!
Cool. Try playing all those scales and modes, but using legato. Play on a clean channel, on a bridge pick up, the tone will sound tinny, thin and weedy, and focus on good sound generation.

Practicing on settings like this, will reveal how solid your fretting hand technique is.

Of course, you're allowed to pick the first note when you change strings.

You say you want to speed up your tapping? Sort out your fretting hand first.

Also, Guitar Techniques forum, please.
Learn songs. This is always my advice because it is a practical, musical way to practice. Of course scales are good for raw speed, but those skills aren't always appropriate in music. They teach you how to do linear patterns and that's about it.

Practice slowly and cleanly. Speed comes with familiarity and repetition.
