Acoustic Guitar with recharging capability

How hard can it be to make an acoustic guitar that requires a 9 volt battery to power the electronics, into a wall wart charged acoustic guitar?

The battery Industry must love acoustic guitar makers that include electronics that are 9 volt battery operated…keeps them economically healthy.

I want an acoustic guitar with quality electronics and quality charging system.

Taylor, Yamaha, Fender, Martin … anyone?
