I know that this may not be well received on a forum like this, but I was somewhat disappointed with the PA and a bit underwhelmed by the FRFR that I heard. I am a big fan of the Axe, which is why I was willing to fly there. When all of the big performers like James Santiago, Dweezil Zappa, and Tosin Obosi played, you forgot all about the sound quality cause these guys would sound good through an am radio. They all really shined. Very interesting people as well.
What really messed with me was walking down the hall to the amp rooms like Friedman, Bogner, Metropoulos, etc and then coming back. The tone coming from those rooms was crushing. Absolutely amazing. I even tried a couple. When I got back, everything sounded a bit sterile in comparison.
Now to be fair, I was there for most of Saturday and some of Sunday, and I didn't see the four cable method demoed. I'm sure I missed some things. Of all of the FRFR monitors I liked the RCF the best. I get pretty good results from the Axe at home. My personal gear comparison is Dynaudio studio monitors with tannoy subs and my Engl power amp to a 2X12 Engl cab. I still love my unit.
On a general side note: Even the best sounding Boutique amps don't totally translate if you go listen to there clips online and compare to what they sound like live. I can say this now that I have. In my position, I am not well suited to record real amps compared to the potential of the Axe. Only having a small studio with limited capabilities, The Axe will suit me better. I get great results when recording and still get really good live results.
Simply put, I was expecting more from the sound in the Axe venue.
To be fair you were listening to amplifiers in small rooms. The FRFR room was huge and sound dissipated very quickly. I think you would find that if you moved that FRFR setup to a small hotel room the sound would indeed be more crushing.
