That's a beauty. Major nostalgia in excellent condition. They are great amps. I have the AH350 MK6 version with the standard vinyl covered case. Case weights almost as much as the head itself!
For me, The MKV would be the icing on the cake definitely. It has a lovely tone to it.
How does it sound with the Barefaced cab?
I always found that the neo speakers didn't suit the Trace too well - Genz Benz Neox, Genz, NX2, Gallien MB212, Markbass Traveller variants etc, but the head sounded ace through the Fender Rumble twin 1x12 cabs, and Genz Focus 15, which were ceramic. Seems like the characteristics were so developed on the neos that the Trace wasn't at it's best. Just my experience.
Having said that, the all of the neo speakers were great with my Markbass F1.
Great find!
