Hell yes it is.
My experience with modelers was the BOSS GT5 back in the mid 1990's (been playing pro since 1978). Then went back to a Marshall stack for a year. Then the Roland VGA7 modeling amp for a couple of years. Then back to tube amps. Then the Line 6 Vetta amp for a year or so. Then back to a real Bogner Ecstasy. Then I got a Helix in the first batch that Sweetwater had back in October 2015. Used that for 3 years. Then went back to tube amps with a Mesa Boogie TC 50 (which is AWESOME sounding).
But a lot of my gigs are "silent stages"...and even though I have a BOSS WAZA Tube Amp Expander and can run my "real" rig with no cab and just straight to monitors and FOH...it's still too damn big to drag through these Casino/Resorts in Vegas. There just aren't any venues with load in docks. lol
So last year I got a Helix stomp and made myself a pretty nice sounding pedal board rig. Sounds great.
But it is now my backup rig.
This FM3 is the shit! My only regret is that I didn't use Fractal Audio gear years ago.
But I'm here now!
