Hi Folks,
I am thinking about a Rumble 200 or 500, among a few other amp options. I got to play a 200 in the store and liked both the sound and the power. The bottom of my pants were flapping a little bit- always a good sign.

I definitely liked the sound of the 200 more than the Ampeg equivalent 1x15 which, to my ears, seemed much more colored. Some people do love that but it wasn’t my thing.
I have not been able to play a 500 yet. (They are in short supply, I know.) Reading here, whenever anyone asks about a 200 versus a 500, everyone says to get the 500. More output for not much more cash. OK by me if the tone does not change too much. (By the way and FYI, it seems as though all the big online retailers have bumped up the 500 price from $500 to $550.) Some quick questions...
-Are there any major tone differences between the 1x15” 200 and the 2x10” 500, other than the 500 being louder?
-How does the 500 (or the 200, for that matter) do with the low B of a 5 string bass?
-How do you get the grill cover off? To tighten down all the screws, which I have read here may need some attention upon receipt. In the photos I am not seeing any grill screws. Does it just pop off if you wedge in a screw driver or something?
Thanks!
