Its true. I am super happy with the Axe Fx. The versatility of the unit in a live setting is what really does it for me. I like a tight rhythm, so I use a powerball / FAS duel amp rig for those super tight sounds, but I like a really loose, Pettrucci-esque lead, so I can use a Mesa amp for that.
Plus parametric EQs to tune the sound to the venue, multiband compressors, neat tricks with highpass filters to keep the low end tight, and more makes it sound great live. Some people might say it gets buried in the mix, but I never had this issue. My other guitarist is still using a 100W tube head, and the clarity the first time we rehearsed with the Axe was astonishing.
For our EP, we will probably mix Axe and a tube head for rhythms, and then use the Axe for all of the leads. Right now, we are just tracking DI using the Axe, and then we will send that to a studio for reamping. No studio time wasted on performance.
Plus, my demos are sounding better and better!
God I love the Axe!!!
