Become a human metronome... that may sound weird, but hey, drummers do it... I mean, watch a drummer play... most of them bob their head and tap their foot (when not holding down the high hat). I follow the same thing with guitar. I usually bob my head at half note speed and tap my right foot at 8th note speed. I don't do this on purpose... in fact, the way I found out I did this was watching a video of me playing. Now, once your whole body gets into the groove, your hands will too (hopefully). Don't try to play memorized licks during a jam, they're for when you're up on stage and you can't think of anything when trying to improvise :) Don't act as if you're playing to a metronome, because it's a band with real live people that don't go "click, click, click, click"... don't think... just play. Did that make sense?
