I play rythym guitar in a progressive rock/metalcore band and i am fairly good with rythym and chords but i am not really as good at lead as i want to be. How can i get better?.... practicing, scales...?
do alot of scales and learn to alternate pick in a very fast manner. The song that helped me a lot with this is "Killing is my business... and business is good" by Megadeth. For whom the bell tolls by metallica is also a good song to build up lead strength.
