Hmm, I think you're talking apples while G-dog and I were talking oranges. I was referring to the Rumble club on Talk Bass, not about people owning Rumbles being judged by those who don't. I've not heard of people with the Rumble combos being given grief for their amps. I'm sure it happens, but I've not seen it first hand.
For me, I love to hear about different equipment from mine, and I don't think I've cast aspersions at other folks' amps. That was why I followed the link over to the Rumble Club. On that page at least, there were some very snarky and pedantic posts, and that made me run back to the friendly Combo Club. My Doggy friend clarified by putting what I saw in context, and so here we are.
If you like it, play it! If it sounds good, turn it up!
