This is my set up for recording vocals.

My problem right now is the volume level when I plug in the microphone is incredibly low, especially when compared to the volume when I use a guitar. I've turned the knob to the maximum, turned every volume setting in Gearbox to max, and it's still too soft for some of the presets. I've even tried maxing out the gain. No significant effect.

Is this normal? Or am I doing something wrong?
