g'day guys, a quick search didn't show up a thread along these lines so I figured I'd start one 
My experience with Tech 21 started with the SansAmp BDDI - something that I don't consider to be an effect. I used mine as my main tone-shaping tool back in the days when I owned a crappy Jade Systems Australia solid state amp. Sound engineers were well happy to plug into it at gigs too, and I got heaps of compliments on my tone.
When I put my rack together, I chose the SansAmp RBI to be my pre-amp, and love it's tone and versatility. The addition of the mid dial just improved on an already good thing. Again, soundguys give you much respect when they know they can get a good sound so easily. Our latest recording had me using the RBI straight to the desk, and it really does sound like a honking great bass rig on the recording.
Just recently I picked up a used Landmark 300 head, to use in my Kate Bradley gigs, but it turns out it packs enough grunt to keep up in my band too. So now I have a good 'emergency' rig, which is small enough to fit in the rear seat well of my car should things go all pear shaped. The dual channels are great, I find myself using the blend mode for some amazing tone shaping. Still getting to grips with it I guess, but it's pushing my tone towards something radically different from my RBI.
My only regret? Selling my old BDDI to fund my upgrades - it's always nice to have a little extra security, because as we all know: the show must go on
The BDDI bailed me out of two near-disasters, and I was sad to see it go.
