@fr4nk – I would leave D2 & D3 empty and connect the RotoTone across D1. Then on the RotoTone PCB you set up 4 different diode clipping configurations. See the attached image for examples. (And remember to socket the diodes on the RotoTone PCB so you try different diodes and configurations. Also note that different diodes have different Fvd (“Forward Voltage Drop) and some of the configurations may sound louder or quieter [allow more or less volume to pass] depending on the total Fvd across the different diode combos.)
Hope this helps.
