I'm pretty much a prepper in life. I bring all kinds of "plan B" (C, D, E, F, etc.) options with me.
Me too, if I can.. If my GM-400 had worked, there are patch modifications in it so I could have coped immediately with poor sound in various ways. Would have brought a backup GM-400 if I thought I'd need it and could have carried it.
The way the day had already (not) shaped up, I decided it might well be a test of character, it was going to 'examine my technique'. It was a near-perfect example of Sod's Law too, a switch that had worked for 14 years, never glitched, worked three times while testing in that same pub, failed right before I was due to go on.
Best laid plans of mice and men...
I later realised it must have been flaky and got knocked into instability as I carried it up the hill to the pub. Would have been nice if it had let me know the moment I tried it on arrival, but never mind.. It will work next time.
I think what you said counts as tactics, so more effective. Versatile...
Another guy posted earlier, he was in USMC boot camp and said that, and his dad said something like 'perfect planning prevents p...-poor performance'. Definitely true, and I bet training helps (as in learning and practise), but then I think (to paraphrase Gilbert Shelton) that tactics will get you though times of no strategy better than strategy will get you through times of no tactics.
