Okay, so now, initially I had a problem with the footswitch not changing channels. I found a mic cable that worked with it. Not all my mic cables I tried worked with it. So, that was remedied. NOW, when I went to practice, the amp didn't make sound, the fan wasn't working and the footswitch didn't work at all. None of the lights on the footswitch would light up. What's going on? I checked the two fuses, but they go to the tubes and the tubes were on and the fuses weren't blown. Is there another fuse somewhere for the fan and footswitch? I have a gig next Friday, the 18th and need it to be working. The amp isn't even a year old; got it last May, towards the end of the month. I've filled out the service request form (on the Egnater site) yesterday or the day before asking about the footswitch and haven't heard anything back. I filled another out for my current problem. This is disappointing with the Vengeance, as I love the sound. I luckily have aTourmaster 4212, but really don't want to have to use it for the gig next week. I shouldn't be having problems with an amp that's not a year old. HELP!
