Ive also been playing for about 2 years now and something that really helped me gain speed is my good friend : The metronome
Just get yourself one its a good investment.
A good exercise t do with it is playing chromatics on 16th notes. Its great for finger independance and speed.
Even playing through ur scales(alternate picking and with a metronome) will increase speed.
There are countless amount of exercises that you can do with a metronome to increase speed
Rock on!!!
I wanna ROCK
