it took me a few days but i finally got the tempo and chord switching down on the intro to when i come around by green day. i know how to palm mute, but when i pick the muted strings it doesn't sound as "crunchy" as green day's version. my pick tends to get stuck and it sounds like a plucking sound rather than that metal sound. i rock a micro cube with the gain and tone turned all the way up. is this an amp issue or a technique issue? maybe its both.
sounds to me more a technique issue.
^+1.work on that muting of yours.
could perhaps be your guitar sound/equipment cos they're probabaly rockin several pedals and such. but the suspect is much likely technique
well i turned the volume up a bit, sounds a better but yeah im pretty sure my technique needs work too
