Had one, early model. I liked it a lot. I used mostly the green channel and the yellow channel. Red was way too over the top for me, gain wise. It got very very hot when run for more than 45 minutes or so. The knob on the treble pot got broken off at the base of the shaft, by a bungee cord when I packed the amp in my car. Took over 3 months for it to come back from the authorized Marshall repair place. Developed a nasty crackle that I could never get rid of. Stupid pots and tube sockets are mounted on the pc boards. Sound great until something needs to be replaced, then it is a crapshoot.
Vastly overpriced, new, you are paying for their legacy, not their quality.
