No, the 1176 is a FET compressor, not a VCA. The main difference being that the FET reduces gain with transistorts, providing a grittier and more distorted compression, whereas a VCA would uses a control signal to determine whether gain reduction will be applied. VCA compressors are usually a lot smoother and brighter than FET compressors. An iconic example of a VCA unit is the classic SSL bus compressor. These two types of compressors are both incredibly fast in action, but the way they react and sound is very different.
