I'll third that, If the AxeFX IIXL was just as transparent as the FX8 (and relays would be the icing), I could just buy it with the MFC and it would take care of my gigging with tube amp needs as well as my home recording studio needs. Also it's grid function and extra CPU (as well as SYNTH and Quad Chorus) would give me some advanced programming effects abilities that FX8 doesn't have. So even effects wise the extra CPU would make me want the Axe over the FX if it was just as transparent.
A $3000 investment and my live gig effects needs AND my studio needs would have been taken care of. As it is, I've spent $1,300 on the FX8 for live use and would still need to spend an additional $2,400 for the AxeFX to use it in the studio. As it is I am also considering a torpedo live as then I could record my tube amps with FX8. Realistically though, I am still leaning towards getting an AxeFx (or maybe some other modeller if it does well enough) in order to record at least scratch tracks. I don't like the idea of leaving my tube amp on all day just so it's ready when I want to punch in some sounds on the recording.
The new Quantum is really impressive too.
I think me and a few others are in the same boat. We had money to buy an Axe, we bought an FX8 instead because of its usability with tube amps, but we are within the 15 day return period and are having to justify getting a less powerful product just because it works better with amps. The flagship is in reach if we returned the FX8.... and ... dang it.... Quantum! Lol...
That said the FX8 is a great unit, the relays really open up some possibilities, and I've resigned myself to probably just getting an AxeFX II XL+ sometime in the future.
........ Quantum has made it harder for us new acquirers.
