The idea:
To "re-purpose" V2 in that V2b becomes the "added" gain stage between V1b and V2a. This is achieved via N-Mosfet source follower replacing the cathode follower.
In doing some reading, thinking and simulating (not yet tinkered), I have arrived at what I think might work...at least in simulation.
Sure, I could "easily" add another tube, but the goal is beyond what is easy.
A second set of eyes would be appreciated to poke holes in the concept and design. Schematic of pre-amp to tone-stack attached.
Thanks in advance for your insight...
