I have the Flyrig 5 v2 also and love it. My usual rig is either a Marshall or Mesa, but played a couple of shows with the Flyrig earlier this year at small venues where load in and setup time was at a premium.
First was an oldies/funk band at a winery and the second was with a dirty rock band at a dive bar in Hollywood. Load in, setup and brief sound check needed to be 10-15 minutes between bands.
I liked how I could send the 1/4 output of the Flyrig going to a clean amp and cab onstage and in parallel also send the XLR out to the FOH PA. Giving the XLR out to the sound engineer let him quickly optimize the levels during our first numbers as the sound check time is so brief at those venues. Both the Plexi and Cali tones sound good, and could get into the ballpark of the tones I like to use. I think I prefer the real amp tones but in a band mix at a live show the Flyrig sounded good. I love that I can show up with a guitar, the Flyrig and a maybe couple of pedals and sound good. I also bring the Flyrig in my gig bag to every show or rehearsal, in case my main amp has issues I can just run the Flyrig through the PA.
