I've been playing the guitar for about 8 years, but although i've developed quite a bit in my playing, I always find it hard to know how to warm up good before a gig, practice or even just a jam. Often I just play a few scales up and down. But I've found that I cant play any good until about 20-30 minutes after we´ve begun playing. Please help me if you have any good ideas on this..
