I just got my Ultra, so I'm only using 4 or 5 at the moment, but I keep hearing the AC30 on cleans that kicks my butt... gotta make a patch with that too... and then there.s the SRV imitation presets.. makes me wanna play that... ( and I'm not really a Blues player...)
The point is, is the models that it does do, it does REALLY well !! Every person is going to pick different models as to what is their favorites... the Uber is wood inducing ... then you start to do dual amp setups, and HOLY CRAP !!!!
Then, if you add in intelligent harmonization, and all the other built-in effects ( if you're into effects..)... and consider how MUCH you would spend on buying all the different FX units, and the killer amp of your choice... the Axe seems pretty dang cheap.
THEN, if you consider that you can get a 2, 4, or 6 space rack, plug it DIRECTLY into the PA, and NOT have to carry the heavy tube amps, cabinets, etc... it's a back-saver too !!
I wasn't blown away by ALL of the presets, but when I auditioned a few that sounded pretty darn good, and modified them to sound the way I would make them sound in the studio... HOLY CRAP !!... then Jason shows me the "boost" option on my amp choice... the silent tuning mode... all I can say, is that my Korg DTR-2000 is for sale, my Mesa Quad, Rocktron Chameleon, Mesa 295 rigs with full FX systems are now fully RETIRED.
