Not to jump on the fanboy train but I agree with Paulzx to a degree. As someone who owns/has owned many Line 6 products including two Helix's, a Kemper, Boss GX-100 and an FM3, I tend to agree that
the available tones in the FM3 are great if not superior to what I can get from other units. I have gigged and recorded with them all and I am no bedroom player, although I do play a lot in my office
Anyway, I sometimes play by Boss GX-100 for extended periods because that is my main rig for church. I love it's flexibility and it is built like a tank and always sounds good. I just came off a couple of months of that. I have done some live gigs in between with real amps and pedals too. Now I am back to the FM3 at home, working out some new songs and doing some demos and guess what? It is a frikken amazing sounding beast! Nothing else I have matches the depth or "realism" of the sounds I have setup - FOR ME. The Boss is fun and is great for my in-ear church gigs. The Tonex is fun to mess around with but if I am going to go through all of that with pedals and such I will just plug into one of several amps I have. The FM3, well it made me sell my Kemper which was the previous king of the mountain for me. The Helix...everytime I plug into that thing I struggle to get the same sounds I get with the other gear. It always sounds flubby, fizzy, and fake to me, and it just never feels right. In the past I have gigged with it a bunch and thought it sounded ok but I think my ears have evolved and what was once "OK" is now "suck" lol. Anyway, use what makes you happy and don't sweat it, and thank you for your service OP.
