So there I was at practice.
I had my Kemper with Camplifier 290 going to two Kabinets.
At a break I hung up my guitar on the wall, bent down and instantly got a bad leg cramp. I made a desperate knee jerk reaction and kicked the speaker cable on one of the Kabinets.
After getting up off the stage I saw that I'd wrecked the input jack on the Kabinet. DOH!
At home I took the back plate off and saw that there was a circuit board as opposed to plain wiring to create the series output. Hmmm...
I contacted Kemper, sent them pictures and Kemper USA got back to me in a day or two. I had asked if I could just buy the board.
Yup!
Less than a week later and here I am back in business!
Thanks Kemper, you guys rock!
