Who here needs a warm-up to get out any sound? Who doesn't? What kind of warm-ups do both kinds need? How does it help? I've been experimenting for quite a while now and would appreciate suggestions on warm-ups (right now, I start at 100% and need to warm-up to keep it up there for as long as possible. If I don't warm-up, I go down from 100 fairly quickly. But some warm-ups, I've found, do more harm than good). Thoughts?
