Have you ever tried the A-136 Distortion / Waveshaper ?

It has probably all these features available. The incoming signal is divided
into 3 sections:

- positive share of the signal with adjustable clipping level and
positive/negative amplification of this component
- negative share of the signal with adjustable clipping level and
positive/negative amplification of this component
- original signal with positive/negative amplification

Precision rectifiers are used for the pos/neg shares in the A-136 (not only
simple diodes). According to the control settings of the A-136 controls all
suggested rectifier functions and anything in between are possible. I know
that the A-136 is a bit underestimated, probably because it's not very easy
to understand.
Only the offset controls are missing. For this external modules (e.g.
A-129-3 or A-138c) can be used. DIY's could add 2 or 3 potentiometers and
sockets with switching contacts for the offset functions. If someone is
interested I will email him the schematics of the A-136 (not a big secret
for an electronic technician).
