Me too... all of my guitars have a variety of resistors and caps so that they stay pretty consistent. Without those circuits I find that the guitars darken up too much with an amp as I back off on the volume and the gain goes down.

It definitely is something the 11R does differently than what I'm used to, but that certainly doesn't make it wrong. I suspect that if I used several different amps like that I would find inconsistencies that way as well.

I do notice that using the 11R through Cab IRs the effect is not nearly as pronounced. And since I prefer the sound that way and have a way to play live that way (with Torpedo Live) I think I'm going that route and it will be a non-issue.
