Honestly the disàppoinment you felt on axe 2 I get on hd500. It was advértised that you can create a chain as your heart desires. But I run out of dsp very quick, and to get a good sound you needed at least 2 eq in a 8 effects chain. As for the jcm 800, personal taste I agree with the op. The jam 800 of xt and x3 was really great sounding, as well as the modern high gain. I can not replicate these sounds on any other unit.
