I guess this amp will come in super-useful to users of other modellers, but for the axe-fx, well it's just not needed. The Axe-Fx needs a neutral sounding power amp on the end of it, not a valve amp that imparts it's own tone on proceedings. all the tone, be it pre or power can be dialled in. Anybody not getting the right sounds out of it probably just hasn't found those ideal settings yet, so they think a valve power amp is the missing piece of the puzzle. So glad I ditched my VHT when I did. It sounded really nice, but didn't add anything that the Axe-Fx couldn't do all on its own.
That's just your opinion. I use a vht 2150 with my axe fx.
Why? Because NOTHING else came close, not even the matrix stuff for me.
IMO tube power and real cabs are the only way to go for authentic sounds. The axe cannot yet create the symbiotic relationship between power amp and speaker . It does not see the load presented. At this point I'm measuring drivers with a woofer tester and setting my speaker values that way. Still not perfect.
I do not use the power amps in the axe. Doubling up on the frequencies is not natural and sounds ultra hyped. Having 150 preamps is amazing to me. Those who think all the high gain preamps sound the same this way have no ear for gain structure or voicing. They all sound considerably different albeit less so than with the power amps included.
It also has me tickled pink that fryette has decided to add a valvulator into the amplifier.
I have been using a cathode follower of some type in front of my axe since the ultra. The complex symbiotic relationship between pickup and first tube grid is wonderfully emulated by the axes front input. Using a cathode follower into the rear input has always sounded better to me. Real tube grid and no special sauce. Real amplifier front end feel because it IS areal.
I will definitely buy one. This is the only way I would use the power amp sims with my axe, with an FRFR power amp. Really excited for axe fx 3 as I think these are some things cliff is already working on. He has mentioned thinking of ways for the axe to be load sensing.
Make note nowhere have I said the I dislike my axe. I love it and sold eight high gain heads after getting it. I am not a fanboy however, everything has it faults and can be improved. It's one of fractals mantra given the firmware is constantly updated.
