Mark IV reverb with foot switch HUM with out NONE

[dual rec king]

Hey every 1 I have a ?. When i use the reverb on my amp without a foot switch I can put it on 10 it works it sounds great. Then when I try to activate it with a foot switch I get this hum no matter what level the reverb is on and it doesnt get worse if i raise the reverb or lower it. My thoughts are its my Pedal? Im using 1 that u have to step on hard and it clicks into place Like on the Mark IV foot switch the Equalizer type button. Do i need the 1 like on channel 1 ? that u just tap?


Thanks

I don't quite understand your post, but does your amp continually hum after the reverb has been switched "on" via the footswitch? Does your reverb behave the same when you engage the reverb on the chassis (instead of the footswitch)?

I have the exact same problem, let me know if you figure it out.

I troubleshot it a bit and here is what I have found.

When using a footswitch, the position that turns the reverb on is open. I found this out by using a meter and measuring across the tip and sheild of the footswitch cable. It is when the tip is shorted to ground that the Reverb turns off. And here I have no hum.

So theoretically, when the footswitch is in a position where the tip and sheild are not shorted, it should be the exact same as simply sticking a patchchord into the the reverb connector and leaving the other end in a way to make sure the tip and shield are not shorted (hanging in mid air ofr instance).

When I do this there is no hum.

So I'm a bit confused as well.

My footswitch has a very long chord. I was almost wondering if perhaps it was the length of my chord causing the problem. I have to believe it is not shielded. Maybe there is some noise coming in on that.

I don't know.

Does the hum go away when the footswitch is disconnected?

Yup!

If you are talking about using the 1/4" jack on the back, then try using a guitar cable instead of a speaker cable to the footswitch.
