Where can I find a stomp box like this?

(It’s a Cajónón.) i was about to answer, untill i watched the clip.
So, no, i can’t help you there…, hopefully someone else, since i am interested too.

This guy is awesome.

It looks like a box with some metal junk hanging off it with a microphone inside. I did something similar once.

Can’t edit my answer anymore, so here is a good link to that Cajón.ón

So just put a mic in a box and hook up to amp or something?

I’m not seeing any stomp box of any kind. Maybe I don’t understand what you’re looking for.

@Axemusica I am not sure what it is called, I have a video for reference.

@rebbel I do not understand what your link is suppose to show a bar graph??

@an-Steve_A-imen
I put a flawed link first, then i tried to correct it and did it wrong again.
So, here’s number “three”

Edit; try this http://en.wikipedia.org/wiki/Cajón
