May explains the challenge: "Gary sings and plays with a lot of passion and adrenalin, which works the vocal audio chain to the limits. He also likes a high guitar level on stage, so when he walks away from the microphone, the guitar sound floods into the mic, which means a lot of riding the faders for me. I’ve tried every kind of compressor on his vocal and none has ever really done the job of managing the dynamics without compromising the energy of his performance or the sound quality. SiDD goes a long way to solving that problem; it’s simply a brilliant product."
