You never can have enough modules that influence levels, whether for audio signals or control voltages.
Vermona quadroPOL is a four-channel polarizer module that can attenuate any incoming signal, in phase or out of phase. One of its unique features is the way each channel's level control works: instead of having one dedicated/detented zero point, it instead has a 'dead zone' where the input signal will be completely suppressed. Thus, you will easily find the off position, even without a center click.
Do you have 10hp of unused space left in your eurorack system? You should consider getting a quadroPOL module! It is so versatile that it's hard to live without once you've gotten your hands on it.
