Be aware, @raul, that the Bassman 800 and the Rumble (Stage) 800 combo are apples and oranges!
Yes, the Invalid Link Removed head is a very modern hybrid with tube pre-amp and Class D power amp. Its retro looking physical design belies its very light weight. But it does have the famous vintage cut-only analog channel for that classic tone, in addition to the modern active overdrive channel for just a touch of warm fuzz or flat out distorted crunch at any volume level. Very straightforward controls, FX Loop & XLR Out. It is the highest powered currently produced Fender bass amp at up to 500W continuous into just 8 ohms, requiring at least a Bassman or Rumble 410 for worry free rating match. I actually enjoy my Bassman 500 hybrid very much with a single Bassman NEO 115 cab.
But the Invalid Link Removed combo is a whole 'nother animal, with its small size, light weight, retro styling and fully digital controls for all modeling, all the time. It comes preprogrammed with 100 different voices & tones of various Fender amps and other brands, with lots and lots of built-in pedal effects and speaker cabinet models that you can arrange into thousands of configurations! If you like tweaking such flexible gadgets, fully controlled even on your phone or tablet(!), then this is your Huckleberry for myriad sonic adventures. And its up to 400W continuous into its internal speakers @ 8 ohms all by itself. Add an external 8 ohm cab and it needs to be rated for another 400W continuous, too (which the Rumble 210 can handle, even if not formally rated as such). Or you could add second 8 ohm cab tor reduce the power distribution to just 267W per cab, or a single 4 ohm cab to handle up to 533W continous.
Actually, the Invalid Link Removed head is more comparable to the Bassman 800, with its straightforward controls, FX Loop & XLR Out. But it has no tubes and no vintage cut-only analog channel, and no retro looking "big head". But its got some very versatile settings, including built-in adjustable overdrive and Vintage, Contour & Bright voicing buttons. It's "just" up to 400W continuous into a 8 ohm cab, but its 800W continuous can drive 4 ohms, 2,67 ohms or even 2 ohms all night long. That's up to four 8 ohm cabs for a whole heap of SPL!
Even the Invalid Link Removed combo could give you what you're looking for in a less expensive, straightforward rig to work well with your existing pedals. Its 350W @ 8 ohms by itself is quite enough for lots of venues, but an 8 ohm external cab brings out the full 500W for outdoors or big venues quite efficiently. The combo and 210 cab make a very balanced load-in/out. I added a Bassman NEO 115 cab to my R500c at a couple of outdoor venues with my loud country band and it was a bit of overkill, but fun!
Hope this helps.
