What you mean is how to smash an egg Auto, just get some dynamite, smash it with a sledge hammer or just run it over with a car, you know i like eggs bro but there are plenty of crap ones just like 80's boomboxes....hope you are keeping well son
I watched a few of them, interesting stuff, I love it when guys get creative with the equipment. Back in the 50s-60s there was a similar movement with homemade guitars and heavily modified amps.
