Almost identical to what I use. Add either a Boss PS-6 for a little pitch shift, or a delay for a quick slap back. These should be always on for thickening. Then add another longer delay to kick on for solos.
It's all in the amount of time it takes to warm up. At my current age, it takes me about :30 before I stop feeling like I have two left hands. My son can not touch the guitar for 3 days, plug in and shred immediately.
I would agree. Most important two things to playing fast are light tough and relaxation. I have to constantly remind myself of those as every time I focus on an intricate run, my tensing up f's me up.
