In a Doepfer keyboard I once had there were just normal potentiometers.
Of course, the whole 270 degrees range of the pot cannot be used that
way. Recently I bought a replacement pot for a foot pedal with 90
degrees range, this is certainly a better choice for a
pitchbend/modulation wheel. The 90 degrees pot wasn't very expensive.
