I've got a 55 1X12 combo that I run through a Genz Benz G Flex cab. It's a great amp with el34's and an eq in the loop. Mine will certainly not be going anywhere.
I can't believe that I ever went from a mark iic to a nomad, I had a love hate relationship with it for 5 1/2 years until I wised up and bought a mark iv. I still sometimes go back to the iic for a change, but I've never missed the nomad even once. They are definitely nothing special, if a little harsh sounding. Save up for something good instead.
