The red LED indicator next to the compression control will show that the compressor has been engaged, (the signal has crossed the threshold for the effect to start compressing). The knob itself is a "blend" or "mix" dial of the effect while the LED will show when signal is actually being compressed. In other words, if you turn it all the way up, but no signal is running through the channel, the light will not be on until signal comes through again.
