Practice, practice, practice! Scales are great!

Learn some metal tunes, and practice every day.

practice practice, the way i practice, just play an hour a day at least :)

Practice with a bass. Put some heavy strings on it. As Tedrillar said, learn some metal.

Once you get fast, throw some lighter strings on it and you will get really fast. The acoustic isn’t going to help much with hand strength or speed.

well, it also takes time, don’t think you’ll be fast in a year, it takes tima, and patience, and playing @ 1 in the morning

It’s going to be difficult if you’re practicing on an acoustic guitar. Practice is the key, and it helps to find a particularly difficult (and fast) song and learn to play it perfectly.

start by getting a bass

sounds so stupid to say practice but it’s true. If you really love it like i do…you won’t see it as practice but as something fun. Does that make sense?

KEEP IT UP!

Yeah, it sure is fun.

The thing is that I don’t take lessons, I just try to play along with some songs. But I really want to use two fingers for ska-music etc.

I used to take classical (spanish) guitar lessons and play bass on a metal band… one of the things from the classical lessons that I think helped me the most to my bass playing was practicing a spanish piece (called Malagueña) that had a lot of tremolo

picking hand or fretting hand? If you’re asking about fretting hand, do yourself a big favor and use ALL four fingers. They’ll hate you at first, but I’ve talked to SO many guys that cheated and excluded the pinky, and they regret it big time ‘cause their range and speed is now so limited. hope that helps.
