I was introduced to the need for impedance matching early as young self selected audiophile. Later got more serious during school for audio engineering, but then as my interest in sound got more serios when it concerned guitar amplifiers and a variety of magic smoke, impedance miss matching, became and remains a thing for me. Add in a german copy of a fender bassman that allowed for 5 different input voltages ,two levels of gain not counting three frequency gain controls and switching between two different, non standard speaker impedance settings, and well, it's the tone that counts, and there is nothing like an amp doing it's utmost to fry everything, but built just strong enough to take it. 99% acoustic these days as the tonal control is so imediate, and just going for it involves less police, who I might add are useualy quite relaxed and good about it. My point is that impedance miss matching can lead to resonance, and that can be a good thing, orrrrr it can create too much heat and let the magic white smoke out.
