I don't know if this is the right place, but here goes.

I have a Boss MT-2 Metal Zone pedal. When I turned on my rig to play for an hour ago, it didn't work in some mysterious way. The way it's set up is like following, which it always have been and I haven't changed anything since last time I played and everything worked perfectly:

Guitar ---> DS-1 ----> MT-2 -----> Amp

My DS-1 works, but as soon as I turned on my MT-2, the sound disappeared. I know the pedal is on, because the red light that indicates that is glowing, and it is connected to electricity, so I don't really know what can be wrong with it, because I haven't touched it since Friday, and it have just been laying there since then, and now it suddenly don't work, even though everything looks ok.

It is hard to explain this problem, since I don't really know what's going on. I know it ain't the jacks, because then the DS-1 wouldn't be working.

If there are any more questions, just ask them.

Thanks in advance,
A frustrated Batista
