Just received a Mesa D800, had just reentered playing electric music from upright (Acoustic Image Contra, symphonic music, etc.) after 20+ year hiatus and was not satisfied with the weight of an old SWR 350, although it sounds great (fat sound) I wanted more headroom. The D800 is wonderful, not to mention 6 pounds. Very clean and concise frequency manipulation, its a keeper. Problem is, I now have the SWR that I don't need. Suggestions for selling it?
