I bought a jamhub bedroom unit from a guy on craigslist, used it once for practice, loved it, then came back next week, plugged it in, and the unit just keeps turning on and off and I also smelled a burning plastic type smell coming from the power plug in. There's no issue with the power cable as I believed that was the problem and bought a new one directly from the manufacturer and it kept happening. Anybody ever had a problem like this with a jamhub or any other music gear like this? pedals? etc? Any advice? and if you got it fixed, how much $ did it cost? So frustrated.

In case you guys aren't familiar with the product, here's a link.
