Looks like hopdybob is using a Peavey Vypyr VIP series amp. I am wondering what the speaker response looks like, but it seems like I'm not going to find it. Honestly, it's very hard to get 20W or 40W, a modeler, and a high quality speaker all integrated into one unit for such a low cost, but I don't think I have any real experience with it.

How have you tried setting it up?
