The hard clipping diodes could go right after the 22uF cap after the input stage, but would benefit alot from Another stage after, to bring the level back up, as the clipping will lower the signal volume, so i would add a gain pot Before the diodes, and Another stage after.
Soft clipping, i have only seen done with op-amps. cant really say how well they would work or how to be done with a transistor.
Edit:
Found this at GeneralGuitarGadgets, uses both types of clipping.
