First I have to say that I don't know the CLR.
I'm not quite sure if your approach will satisfy you. It depends on what you mean be "the real thing". If you mean standing in front of a 4x12 with a 100W tube head sitting on top you will certainly not get this. If you mean a properly miced guitar sound then yes!
Going the FRFR way means you will get what the amp sounds like miced. This is what you hear through monitors in the studio or the PA at a concert. You have to ask yourself it that is what you are looking for or if you what the sound you get standing in front of your stack.
