I’m looking almost a year for a MOOG 1120 controller in good condition. Does somebody have one for sale ?

for details.
I think the pot inside is exact the type used as mod wheels in the vintage minimoogs …

I wonder if any brand offers modulation devices (pedals, modwheels) with selectable characteristics. If there is just a linear pot mounted, the characteristic is for linear functional control (or you have an expressive control over your foot 
), where logarithmic pots (taper) are used for volume control (as the human ear hears that way) and the reverse tapers for the left hand users in our world. AFAIK no modwheel nor pedal can be switched...
