dual pole ON OFF ON switch between 3 configurations

Question

I'm designing a circuit (guitar effect) and have reached a point where I have to switch the signal path between 3 configurations involving a pair of diodes.

The circuit's 'out' path has the option of going:

1. Straight out (uninterrupted)
2. Through a pair of parallel diodes (symmetrical clipping diodes)
3. Via one end of the diode pair, with the other going to ground

I have a dual pole on-off-on switch that I would like to use if possible. The schematic currently looks like this:

Is it possible to switch between these three with a simple switch or will I have to use a rotary switch?

As requested, the three I would like to achieve:

CONFIG 1

CONFIG 2 (note diodes must be NC)

AND CONFIG 3

Answer 1
