On my breadboard, sits a new modification to the Omega Boost.



You'll probably notice that with the 50k pot at center, we have made no change to the RoG circuit. The bottom half of the voltage divider is 33k, the top half is 68k and the total is 101k.

What changes? Well, to my ears, ccw (wiper towards V+) sounds a little more relaxed / vintage, while cw (wiper towards Q1) sounds a little more pushed / modern. Now, the signal is getting attenuated / boosted as we move through the sweep, so it could be entirely psychosomatic. Personally, I think something else is going on when the wiper changes the voltage at Q2's base, but that's beyond my analytic abilities.

Maybe someone else out there will try this and find it useful.

Nitpicking here, but you have the JFET depicted as a P-channel.
