We did a similar trick in the A-106-1 and replaced each clipping diode by a
potentiomer + diode (connected in series). This allows to adjust both the
positive and negative clipping level (CL+ and CL- controls of the A-106-1).
By using the universal vactrol module A-101-9 both parameters can be voltage
controlled (potentiometer + vactrol output connected in parallel).

The corresponding diodes are labelled D3/D4 in the original Wasp schematics
of Electronic Dream Plant (EDP) and D1/D2 in the A-124.

b.t.w. We added a mod to the A-100 DIY page that allows self-oscillation for
the A-124.
