Single diode to ground for asymmetrical hard clipping - Not possible?

[lowpitch]

I was experimenting with the below Rat circuit (Aion FX Helios). The mode switch is on-off-on. I took out the LEDs (D8, D9) in order to only hear the op amp clipping with the switch in the off position. Another mod was taking out the diodes D4, D6 and D7, leaving only a single 1N914 (D5) connected to ground in another switch position. Before, with the LEDs installed, this lead to asymmetrical clipping with one 1N914 and one LED. Now with the LEDs removed it seems there's no difference between the off position of the switch and the position with the single 1N914. I checked for continuity from R5 to D5 and the switching works.
So, does a single diode to ground not do anything in terms of clipping? If so, why not?

It should definitely work. I can’t imagine why it wouldn’t?

That appears to be it. Thanks for the link!
