I wanted one of these since I started on the Egnater /Randall amp pathway, but chose for practical reasons to go with the rack mount preamp, which I am still more than pleased with.
My last attempt to go with a modular head was the Lynchbox head and 4x12, which was fun but not practical.
The thing that made this of interest is the low output setting , which sounds really good , along with a very good master volume that doesn't spoil the sound when dialled down.
This belonged to a friend who had had a change of living circumstances resulting in this clogging up his parents home, and he wasn't using it at all, so after a bit of horse trading it is now mine.
I kind of wanted it so if I do any guitar shows I will have a head to use for them - maybe need to team it up with a Zilla 2x12.
I certainly have enough modules that I can use on it.
Think I'll have to rig some of the FX units from my rack so they are easy to patch into the amps loops as I like a little reverb etc.
It can take a variety of tubes and is currently running a pair of Russian EL34s.
The only poor bit of design is that the weigt is a bit at one end of the head due to the positioning of the transformers
