I made a thread earlier this week about a rig for college. I have been playing more and more jazz and have decided to get a rig more suitable for jazz volume levels, not rock. The wizzy from EA has intrigued me for a while now and i have read everything i can find on here about it. What light weight heads are good matches to this little cabinet? Mind you im a college student and dont have a ton of dough, so my budget is around 500 or so for a used head. The eden wt-400 has popped up on the classifieds a few times for around my price range. Is the wt-400 as warm as the wt-550 i have played through? Also, what wattage/rigs do you play through in your jazz groups?
