I want to believe...
For two years I've been trying to make the case for this on my pedal board. The promise is basically you can some how never buy new pedals again other than online and downloaded... But, try as I might, I have still yet to use it live. I just can't trust it.
It is noisy. Lots of fuzz comes through the connection. The selector snt always sile t and usually pops. If the wires aren't just right, I get terrible feedback. And, the recording software you can buy is only so so.
I've used a couple other interfaces and they seem to all have these problems for me. I think the tech is just not there yet.
Lastly, I haven't found a way to bias the amp modeling In any of the software options. I'm already playing through a good amp. Adding an amp model on top usually just makes the whole thing muddy (if I can get past the noise and feedback).
If you want a toy to play around with, it might be fun. But I would suggest building up a good collection of real pedals first.
