This module is a great tool once you know how to use it. It can be a vca, mixer, inverter, ring modulator, and an attenuator. Great size, nice layout. The only problem is, when fully suppressed there seem to be a small amount of bleed, so it would not be a good choice if it was to be the only vca in your system, but it's not a massive problem as the bleed is a very low level and could therefore be gated very easily or even just not noticed at all.
