Power an amp and component with batteries instead of direct outlet power?


Hi neighbors,

It is common for guitarists and bassists to use batteries in their effect pedals because the pedals sound quieter and easier on the ear.   

Why not connect several car batteries that are charged enough for 90 minutes and power a transformer with enough wattage for my entire audio rack?  Or buy a budget battery power rig designed to power music racks?

I've heard the difference and using battery power is better in effect pedals.

it would be interesting to use a tesla power pack to run a system. Interesting enough the power wall from tesla is cheaper then PS audios regen power system mmmm ...

What about gas powered amps? Nuclear? Some limitations maybe, but might sound fabulous.
My TW Acustic AC3 is powered by Batteries and uses wall current when batteries are low you can clearly hear the difference.
