A quick "IF" regarding an OCD project

[duck_arse]

Here's a simple clipping option. Note the drain-gate connection (not gate-source):



You can use an on-on-on DPDT switch to toggle between the standard OCD clipping, symmetrical true MOSFET clipping, and asymmetrical MOSEFT / body-diode clipping. The diodes can be anything, but low Vf (germanium) is probably best since the MOSFET Vf is already ~3V.

a person of a perverse bent might replace D1 and D2 with another mosfet each, wired so's their body diode does the blocking of the clipper-mosfets  body-diodes. I don't think the gate connection would matter, then. [I may have confused myself, here.]

What I wanted, though, was to merge diode (or mosfet) clipping and tube-analogy transistor overdriving.

An off-topic different design could be to include diode or mosfet in NFB loop of a "conventional" BJT..
(in a Big Muff style like below..)

Hey, this looks way different. Very interesting!

That doesn't look quite right....
(Mostly because I haven't seen a diode-connected JFET before).  Interesting, indeed.

The Mad Professor likes to do the funny jfet thing in lots of his designs.....
