I do not have a terrible case of G.A.S, however I am keeping my eye out for a new bass head to replace my Peavey Tour 450. I am looking for something with a little more power, but also not a powerful price. I would like to go tube this time around. I have found two all tube heads that have caught my interest and I have done some Google searching and found some info, however I thought I would ask the knowledgeable TB community here for their opinions of and any experience anyone has had with these two heads. The first is a Peavey Classic 400, all tube. The second is an Ampeg Jupiter 22 is what it is labeled as on the head itself. Just curious to what others have to say about these heads and which would be a better choice or should I just stick with my Tour 450 at this point? My cab is a Mesa PH610. Thanks everyone as always!
