I probably used the wrong term! It was a female singer, guitarist and drummer.
With hindsight, I suspect the limiter was turning the signal into mush and that
was masking the singer. It didn't seem to have as much effect on the guitar,
which was quite heavily fuzzed.

This was a good few years ago, and they were using all analog kit. In fact, I
think it pre-dates me getting my first synth, an SY22 :o
