You can’t have enough VCA thay all said. Well this one is a dual VCA with a mixed output. The VCA it self I do like and use it a lot in my patches. This was one the the DIY version of Erica product I did like to build. The spacing of the components is fine one this one. I have four or five of them in my rack. Not a lot to say it’s a good VCA.
