I'm about to lay some money down on a Gallien Krueger 1001. I'm not sure if it's the older or newer one, but in the instances that it's the older one, I need to know something. What exactly was this whole "defective 1001RB" business? Was this problem only in the older ones? Did they fix it with the new ones? Was it a very common problem? Did it only happen within the first few months? Also, does anyone know what date the new II models were introduced? If I bought an old one, should I worry? If it's the II, should I worry? I have to go through some dirty work to get this, so I want to make sure it's going to work, especially because it's used. Thanks.
