If so, how'd it sound? Is that amp enough to power that cab sufficiently, or does it seem to be "lacking"?
You have one or the other already? 500W amp should be quite capable of giving 212 a hard time. You will struggle to gain attention of the target audience of the three TB bassists worldwide* with that combination. *madeup statistic.
There wouldn't be anything lacking with that setup. In fact, you could easily irritate a sound guy at a gig with it if you weren't judicial with the volume knob.
I have the VT500 but not that cab. I have 2 Hartke Hydrive 112s. The VT500 isn't lacking. I'm keeping up with two guitarists and have a ton of headroom to spare.
