This kind of thing always makes me smile and wince in equal measures.
There is no gunfight, there is no showdown, there is no drag race that anyone needs to be concerned about enough to worry whether one is 'better' than the other. There is no defence to be leapt at - Scott absolutely nailed it by saying its just a piece of gear!
If it IS 'better' (in itself subjective to a large degree) - why would you care? What difference would it make to you? Will people laugh at you in the street and point at your equipment? (happens to me, but that's a different story altogether, and you don't want to know what they're pointing at). Will you have to hang your head in shame as people will think less of you because something newer/'better' has come along, making you less cool as you no longer own the 'best' piece of kit???? I hope everyone is saying 'NO'!
Ultimately, you have a kick-ass piece of gear that either does what you need of it, or it doesn't. If it does what you need, ignore all the noise, play the living crap out of the Axe and have a nice day. If it doesn't do what you need, then look forward to trying out the KPA when it comes out and giving it a whirl!
As guitarists, we're living in probably the coolest time for gear ever (definitely for me in the 23 years I've been playing). Things are at a ridiculous level already, and I'm sure they will continue to progress. Just IMAGINE the conversations we'll all be having about gear 5 years from now!
Personally, I'm looking forward to hearing what the KPA can do, but it will just be from the perpective of being a gear nut/closet nerd and wanting to play with a new piece of kit - NOT from the perspective of seeing if its better or if I would consider getting one. Why? Because I can't possibly imagine wanting or even NEEDING anything that does anything more/different/'better' than the Axe FX (particularly since I got my II which is, quite frankly, just silly). The AXE II has more power, options and flexibility than I will ever have the talent or the ability to utilise to its fullest. I do, however, wish people would stop pointing at my other equipment in the streets and laughing though but hey, you can't have everything.
Party on dudes (and early happy new year to you all too!)
