I use my modeling stuff for FX too. . So many cool verbs, DDLs, Choruses, etc. I use the QC and LIne 6 stuff in 4CM and it makes it ultra simple to get around sound wise. Maybe it's my old ears, but I had a hard time differentiating between my pedals and their digital counterparts. I find a slight difference in how they feel when playing them, mostly the overdrive/distortion stuff, but I find a slight difference in using different pedals anyway. I am going to get the sound I hear in my head no matter what. It's a matter of how easy it is to get it.
