Have played a Mesa Walkabout with my NV412 for the past year and really liked it. But recently picked up a Berg HD212 and feel it is a much better match for that head. Just fatter and smoother all around - great for my country, rock, blues band. I want to keep the NV 412 - it's such a great cabinet, but would like to find a new head for it, so I can have a big rig and a small rig. I like the tone big, thick, fat, warm and rich - not sterile or super grindy. I play a Sadowsky strung with flats - no slap or pick style and no lead playing. Pretty fundamental and supportive approach. Been thinking about a DB751 or maybe a tube head like a Fender Super Bassman or even a Reeves. Ideas?
