Well the news gets worse. I thought of what @agedhorse said about maybe repairing the bent knob so I plugged in the amp. It never left "Protection" mode. The Eden light, which usually turns green when it goes active, stayed in "red" mode. It never started up. When I got the amp, it was packed in a medium USPS Priority box. The poor guy didn't have a chance. Not enough padding, and on top of that, he wrapped the SIDES and TOP of the amp with bubble wrap, but not the front! Then he used beans for bracing. It was the perfect storm for damage. I kind of schooled him on using more bubble wrap everywhere and a larger box, and buying the extra insurance. Man, when a sale fails for me it really really fails! Luckily if all else fails eBay has a record of our transaction and emails and if he resists eBay will just refund the money. If that happens of course I'll ship back to him on my own dime. I'm superstitious (being Alaska Native ha ha) and I believe there's some bad karma in the amp. Good to get it out of my life. Matter of fact I got it in my shed! LOL
