I just bought a used David Eden DC210XLT Metro combo. I paid $400. It didn't come with the footswitch or casters. I don't know the age on it, but I sent an email to Eden with the serial number to try to get some info there. The guy I bought it from estimated 10 years old. I haven't really cranked it yet, but he played it at a pretty good volume and it seemed fine. My neighbor situation doesn't allow me to turn it up at home. I'll let you know how it sounds when I let it loose at my buddy's. I'm not sure if the speaker off switch and headphone output are broken, but I can't get either to work. Also, there was something funny going on until it warmed up for a few minutes. If I remember correctly (I'll write it down if it happens again), when I was plugged into the 2nd channel and switched over to the 1st channel the sound would sort of fade in and out and there was a scratchy sound. I may have that mixed up, but there was definitely the sound of the bass going in and out and a scratchy sound. I was worried, but I couldn't get it to happen after a little while. And just sticking to one channel or the other seemed fine as well. Does anyone have any idea what is going on there? I'll try to isolate the issue if it happens again. It's pretty heavy, but I can manage it. I did order casters from Eden. Just because I can handle it doesn't mean I want to. I'll give more info on tone and volume when I can really play it.
