Instill use my Pod X3 and still love it. It has a fairly steep learning curve but a lot of control. The preset sounds were janky, but you get nearly anything out of it, if you spend some time.
This may or may not apply to the 500x.
Exactly why I got into recording. (and a large part of why I got out of it)
I don't care how awesome your band is or how many records you sell. I'll do the best job I can and you can pay me by the hour.
