I dont have any warm up licks or songs. I usually just get right into the business of things. But then again, my first song has a lot of simple finger moments that could warm up your hands very well.
But if theres any riffs or licks I enjoy randomly playing, one of them has to be DR feel good or kickstart my heart. My two favourite motley crue jams. Very simple to play for the most part, and so much vibe. Plus the wah solo in kickstart is to die for.
