What amp do you use now ?
Been bouncing around lately. I picked up a Rumble 500 head on the cheap as a backup and have used that a bit recently. I like it's inherent tone, but it lacks in features that I like. Kind of thought the opposite with the D800+. Also picked up a Traynor yba300 that I love so far. While relatively light weight for a big tube head, it's still no 5lb, 500 watt burrito that makes transport a joy.
Ultimately tough, count me among the masses that wants the feature set of the Subway on a higher powered Walkabout...
