Hi everyone. I have a Rumble 200 combo with the matching 112 extension cab. I really like the tone with the extension cab added, enough so that I am no longer thrilled using the combo alone. By itself I suppose I find the combo a bit boxy, although I did like it before I picked up the extra cab. I have been thinking of selling off both of these and picking up a Rumble 500 head and 2 of the 115 cabs. Looking for a second 112 is also an option, but of course those are harder to find now. I guess I'm looking for tone comparisons between the 115 extension cabs and the 15 in the smaller boxed combo. Any experience is much appreciated!
