It's a slash signature wah pedal, there aren't any stores I can take it here.

Because I live in the middle of nowhere.

But before I went to this place, I took it to someone

And he said the issue was a busted circuit

So he replaced and fixed it

I took it home and switched it on, lost my guitar volume

Nothing happens if I step on it, no wah sound

One thing I noticed is that there's no spring I think.

If I remember correctly when I step on it -- it should bounce back

Yet whenever it gets lifted up when I step on it, it doesn't stay up.

It goes back to the bottom because there's no spring

Here is a picture

That's just my speculation, I'm really not sure of the problem.

All I know is that it won't work, and it won't turn on, but the lights are working
