Late to the party, but in.
Had to test another product for myself before deciding.
Joining the waitlist is free. Join first, decide later.
It's what I did (fyi, I was 'in' within 10 minutes of that 'ready, set, GO post').
It seems ridiculous since I've already got the Axe-FX and my FX8 sitting right here, but I'll almost definitely buy an AX8 when my invite comes. Because I think the AX8, for my purposes, can acceptably replace BOTH my Axe-FX and my FX8.
Originally I bought the FX8 for live band use and planned to keep the Axe-FX for recording and quiet home play. Already sold my MFC.
If AX8 price had been closer to 2 grand like I was expecting, I would have passed on it and stuck with what I have. But at $1399, I can't say no.
I know the AX8 will do the job my Axe-FX does now.. I don't really use complex, cpu-hungry presets for my recorded music. Already have DAW interfaces.
I THINK the AX8 will work just as well with my tube amps live, for my case. I'm currently not using the relays anyway, and for 4cm... well it's still unknown whether there will be any true audible benefit to the FX8's 'optimized' signal path. I'll be able to compare directly, side by side.. but my guess is that AX8 will do the job just fine.
