Since you're raising this treatment, I'll add another, perhaps faster, technique I learned many years ago also. It involves lowering the pitch of the individual strings, one at a time. As you lower, "beat" the string vigorously with the hammer repeatedly until the string goes slack, and then do the same repeated hammering as you carefully pull the string back up to pitch. Doesn't require twisting, (which sometimes doesn't change the tone much, in my experience), but almost always gives you a significant bump in the higher overtones also. Something else to add to the general bag of tricks.
