It's quite heavy for sure, but is much better suited for playing with a band. I have an Amplifi 150 and it sounds OK. I tried using it as a FRFR for the Helix. That sounded OK, but only at playing at basement studio levels. The flimsy 1/8" aux jack isn't road worthy - period.
The FH1500 sounds better at any volume to me than the Amplifi 150. The dynamic range is immense and the models seem more realistic. The i/o is extensive, so I'll be able to go stereo into the PA, plus run a monitor signal back into the unit. One less box to haul. The FH1500 is professional.
I'll be trying the FH1500 at some live gigs in a few weeks to see how it compares to my Egnater Renegade and pedal board. The Egnater sounds great, but I'm hoping to be able to be done with tubes. They're expensive and I don't replace and bias them as often as I should.
