Sorry for delay,dunno how but I missed it
So warming up,I use random stuff,nothing prepared or specific,
sometimes it's chord or two,few runs,some sweeping etc.
And I can't show the line between warming-up and real playing,
I just grab guitar and start playing.
There are moments when I go for some really hard exercises/licks straight from the bed,
but result is usually the same one... "Ok,this AIN'T working...coffee first

"
Main conclusion would be,play anything you want to warm up yourself,
some easy solo or nice chord progression,
it doesn't have to be unmelodic warm-up stuff,there are many ways to warm up
while still having pleasure listening to what you're playing.
And it's NOT silly question,just don't make a Taboo from it!!
