I am using the FC-5 pedal.

I have something more to say at the latched Boss pedal.
We are using it to switch on/off our reverb.
Yes indeed it's built like a tank, but there is a small minor problem with it.
It has a small switch located at the back to switch the led on when making contact YES or NO.
I had to solder this switch at 1 position to be sure making contact is always led=on and breaking contact is always led=off.
