Once when I was fishing, my hook got caught and I fought and fought.... massive weight! It nearly broke my rod, but I managed to pull my catch into the shallows. Turned out to be a tank trap from one of the last wars. It was fashioned from old Peavey Mark III - VI amp heads.
They got battered, bruised, grenaded, run over by tanks, set on fire and finally ended up at the bottom of a lake. All of them still worked fine.
It's not the most powerful bass head around, with the full weight of the advertised wattage only available when you run it at 2 ohms load,
but nonetheless sporting the full weight of a massive amp. Don't carry that to a gig that's six blocks away.
I did hook up mine when I forgot to bring my class D head to the rehearsal. With an Aguilar 4x12 setup (at 4 ohm),
I was able to play in a very loud band with a hard hitting drummer, but I maxed it out for that and it barely managed.
