He really really really great sounding big muff. Works good for bass works good for guitar. Original box is a little messed up because the person who sold it to me just put postage on the box and didn't put the box in another box so they don't understand LOL

Comes with the paperwork as seen in the picture

Says in the paperwork it's better than a regular Big mouth plus it's got a boost so you can really really get your sound

Shipped in a box to protect the already messed up box

I don't know if it works on and I will battery and there is no power source provided
