I'm not a huge compressor user. There is actually some mild comp in my amp preset patch. I tried recently to find a way to leverage comp at the END of my chain to get some super duper pumping compressor sounds but was unable to. Putting a pump after thick reverb makes for some really awesome swell effects. You play, stop playing, the pumping compressor swells the reverb up to seriously audible levels almost like a second instrument. I can do it in software, can't seem to reproduce with the GT-10B comps.
With all that said, I can easily run my dry recording back through the GT-10B patches, effects, etc. I'll try to do some more for comps, amp sims, drive effects, etc. While it's easy, it is a bit time consuming.
Baby steps.
