Ditto.
I had to change to the Rumble 500 head (car change), but it was a seamless transition. Pumping it through a Markbass 2x10 102P Traveller cab, and it's awesome. I'd have another one tomorrow if my one blew, without hesitation.
Funny thing, after a recent bass change, I'm now using, on occasion, the bright setting. Just shows after a couple of years, it can still surprise you.
