I've got one coming in a trade right now. I wanted a modern take on a 50w Plexi head and this seems to be a good one. The thing is, I really know little about it other than enough to know it is a good deal in this trade and that it is in the ballpark of what I am after. Can anyone tell me ANYTHING about Bumbox build quality and/or the Lead 50? I see plenty here on the Lead 1, but not much else.
