If it were me I'd skip the custom options idea as it is way overpriced. You can get a much better amp stock for the money. If I were you I'd get a new 2010 Dual Rect Multi Watt. It is a Single and Dual Rect in one, has bold and spongey settings, and diode and rectifier tracking, etc. It would be money better spent IMO. If for some reason you ever had to sell a custom Single Rect you would be out the money you paid for the custom options as well. I saw a used custom RoadKing II on Ebay a while back and it only went for like $2200.00 dollars. I'm willing to bet the guy lost at least $1600+ between the custom options and the fact that it was used. The only way I'd ever get the custom options is if I had an endorsement with Mesa or a huge artist discount through Mesa. Otherwise no thanks....
