Every amp model added to the Axe-FX in the past 6 months is excellent. I dig the authoritativeness in the voicing of the Silver Jubilee. It sounds massive with a band (last night I rehearsed with that one... BOOM!)
too many models, not enough time!
I got to spend some time with the Jubilee last night. I absolutely love it. The model has more bass on tap than the 2550 that I used to have. However, that's not a bad thing since my 2550 felt like it could use more bass. I'm very happy with the Jubilee model!
