I have a Studio Channel I bought on eBay that now needs service and they won't give me service because I bought it used. I guess they are telling us that if we buy used equipment, they will not help or service it. In which case, eBay and Reverb and all music stores that sell used equipment need to be notifying their customers. I suppose the theory is to force you to buy a new unit. But why would anyone buy from someone that conducts that kind of business. You would think they would be happy to have happy customers willing to pay for the repairs. I have been unable to get a hold a manager to discuss this with. Apparently they don't care.
