Contrary to what most here believe. My post was legit. I actually purchased another FM3 recently to give it another go because I don't want to give up on modeling.
I haven't received the unit yet, but I'll be doing more testing once I do. I suspect my issue has been not using the out 1 knob correctly.
As nuts as it may sound, when I load up Guitar Rig 5 and pull up one of the first presets "80's shred" or whatever it is, I can get a full, "loud" tone, even when lowering the output knob on my interface to play quietly. The tone still sounds good. I am thinking because a good amount of output is hitting the interface even when I lower the global volume.
I haven't been able to get the same thing with pricier units. Both Fractal and Kemper. The hardest tone to get is cleans. It sounds weak, and a lot of times I can hear my guitar strings over it. And like I said, some presets, especially those that have a bunch of FX, I can barely hear the FX.
Either there was not enough output signal going out of the FM3 into the interface, or I am just playing too quietly. But what sucks is I can't play much louder, as I tend to play late at night, and I hate headphones, and I live in an apartment.
I hear all the time how these units are amazing for bedroom levels. Also when I hear peoples tones playing through my speakers it sounds good.
Maybe my guitar is crap? Right now I'm paying through a Peavey T-60, as some of my better stuff is in storage.
I also noticed that some presets that I would think would be higher gain, sound cleaner. For example I think there was a fractal preset for "Brown Sound" or "Eruption". I would assume it would be pretty saturated EVH stuff, but I remember loading it and the tone was a lot cleaner and dead, not as much gain as I hoped. And this is a guitar with humbuckers.
I'll be doing more experimenting later this week, and maybe post a new thread.
To be honest, I feel like I can't post anything anymore because I've been labeled a "troll" and I'm not welcome here anymore. I understand that my original post may have been in poor taste. I've just been frustrated that others seem to be having an awesome time with these units, yet I seem to be missing something.
