Well, it's come down to posting pretty much all my gear, and I'll see what goes first. This is the newer 500 watt version, with the "Switch." All of you looking at this probably know about the "AG500 vs. Thunderfunk" thread. . . there's even a "Walter Woods Ultra vs. Thunderfunk" thread. I'm going to ask $1000 shipped, obo. I only got this a month ago and have used it twice at church, so it's pretty much new. It's a monster amp and Dave is a great guy. When things are not as financially crazy I will definitely be getting another one of these. And, if other things sell first, then this is going nowhere. . .
