IMO that's a really extreme measure, and to me it kills too much bass.
Yeah. I would agree that .0022 is the extreme low end value but still gives good tight bass (with bass at 10) when at full gain. At lower gain settings it
can sound a little thin.

0.01uF or 0.0047uF sounds a bit more natural to my ears and doesn't kill as much gain
I actually have .0047 on my normal channel. Gives about 25% more bass, just enough to thicken the sound more without getting whooly. Now the other thing about the .0022 is I think it goes better when cascading the channels. I now cascade the "bright" ch. V1A into the "normal" ch. V1B and so I have very little bass in the first 2 gain stages. Then with the .0047 on the normal ch brings the bass response back in. This really helps keep it tight and not flubby at high gain. I have also added a "fat" switch (330uf bypass on V2A) to bring a little bass back when not cascading. Again just enough to thicken it up a bit.

If you reduce the Mid cap in the tone stack from 0.02uF to 0.01uF it pulls the bass control more into the guitar frequency range.
+1 I was going to mention this as well, as you had helped me with that over a year ago, but I had to go and just posted what I had written at the time. I found that this tone stack mod was a little more subtle and even with that I still found that I would have my bass set around 4-5 to keep it from getting flubby at higher gain. It does however give a good all around bass response in the amp. Turn up the bass to around 8 for lower gain and turn it down to around 4 for higher gain.
So, there are a few tricks to "tuning" the bass response. For higher gain, what I have found is it is better to knock the bass down in the early gain stages and let it back in later stages. This will keep things nice and tight. It will really come down to how you use your amp and what sounds good to your ears.
