Why does everyone keep referring me to the wiki?!?

I'm familiar with the info there - all VERY well done.
But the EQ and effects graphs there ONLY show the frequency response tailoring in the preamp, but do NOT address the effect on the "room sound" of the various Rumbles, in actual use.
For that, dORSY's linked video above is GREAT, JUST what the doctor ordered!
My last post above was about my curiosity about whether the tonal effect of the Vintage button could be reproduced using just the EQ controls, shooting for the same tone, but avoiding the compression effect. Turns out the Vintage button changes the EQ the same as setting the controls to 3 3 12 9.
By the way -
I ALSO did a similar "experiment" to see if I could use the EQ and level controls get my Rumble 100 to sound reasonably close to the sound of my R200.
I use my R100 occasionally when our group practices at an alternate location (another guy's basement), but I can't help but notice that the two amps sound noticeably different.
The Bass Channel video, linked above, shows the difference in tone.
I found that I can get the tone of my R100 close to my R200 (tweeter off) simply by setting the R100's EQ controls to 9 12 12 9.
The R100's output level is almost exactly -6dB lower than the R200, but this can be compensated for, if desired, by increasing the R100's Master control by about 30 degrees clockwise. Like from noon to about 1:30.
The two amps sound close enough to each other using that setting, with or without the Vintage effect in use.
