On a slightly related note, it's interesting to note that the JVM channels were purported to be replications of old Marshall amps, the JCM800 2204 being one of them. Since then the JVM seems to be new Marshall rock/metal standard. It figures, as I had a JVM410H and sold it after I got my Ultra. I could never get a tone I was happy with from the Marshall models in the Ultra since though.
I'm seriously thinking of getting an Axe II because of this new amp model.
