From the post

Doron! I think you meant this one and not the MSL :P

To add a few words, the clipping diodes are placed neatly where you can easily take them on the switch and have your way with them. I would probably go with three position two pole switch and have the middle as diode lift, other end as four 1N4148s (two in series and two of those in parallel for more volume) and other with 2 or 4 1N4001s or LEDs.
