Did some experimenting and I like it a LOT!!
Here's what I did: initially I installed the bright-fat switch. After finding it not fat enough to be very different I swapped the 1uf additional/switch-in cathode bypass cap with a 2.2uf. That was a lot more what I wanted. Overall the amp is really bassy , even on the bright setting. I like that, but not for every situation. The switch I used for the bright-fat switching happens to be a DPDT mini toggle. I only used 1 side for the switching, so there was this spare side waiting to get involved.
Now, I put a .01uf cap in series with the .022uf coupling cap before the gain pot.. but it can be switched out when the fat switch is activated. This means that on the fat setting there is a .022uf coupling cap + the extra 2.2uf on the cathode over V1a, whilst on the bright setting there is only a .047uf cathode bypass cap and the series .022uf+ .01uf = .0068uf.
Sounds really great!!!

Sounds great! A really nice variety of tone (and the demo only scratched the surface of the dirt it should be capable of). Perhaps now you understand why I like ZP's Superlite TMB circuit so much. ;)
