Footswitch killing tone

[SST]

It seems when my footswitch is plugged in it sounds like a blanket has been thrown over the amp. When I disconnect it sounds much better. Sort of like when the difference between hard bypas and the loop on but to more of a degree. Has anyone else noticed this. Should I have my amp checked out?

yeah I would have to say my amp sounds almost dead with loop engaged. Stage I is what I have

Mine has a slightly difference with footswitch or loop engaged but it´s not a problem at all..seems like there aren´t two fives that behaves the same uh?

I'm talking an additional degradation from the loop engaged. Sort of like two steps down and a real muddy sound with the footswitch plugged in.
