I'm not sure it applies 100% but - a Rumblefish could be considered either semi hollow or chambered depensing on how you look at it. The non standard (not wood) top and back are going to have an effect for sure.
Mine display's an more nuanced tone. There's more harmonic stuff going on and a correspondingly less dominant fundamental. It records wonderfully with a naturally complex tone - if you want it. If you don't - put it down and pickup the solid body which comes with less of that stuff and so may sit in one mix better than another ...
Under a clean guitar, percussion and a voice, the Rev works great - In a more complex arrangement, with more going on in the low end, maybe a less complex native tone is a better fit...
