Just get a power supply, problem solved.

There's a famous actor guy who got into pottery and even though his stuff is meh all of a sudden he's an ceramic expert and is mass producing his designs. Kinda pisses me off that those of us who are not already famous have to work 20xs harder to get out stuff out in the world and he just gets a pass because he's an actor.

If you can afford it, properly setup good quality instruments (particularly guitars) are much easier to play.
