Does anyone know if there is an amp for things like guitars and microphones?

do you mean ? it's not a wearable though :c

as long as i can put it in my pet's treasures it works, what's the name of it?

it's just called amplifier c: also you can hover over the image to see the name and have a quick link to look it up in shop search~

Thank you and actually im playing this on my 3ds because i dont have a computer so the hover option doesnt work 4 me XD
