The EMG EXG Guitar Expander is an EQ knob that delivers tone flexibility to your fingertips. The frequency response of the EXG is similar to normal guitar amp equalization. The lows and highs are boosted while the midrange is dipped out. The EXG is great for creating a fuller tone that doesn't get muddy, while keeping it clean and clear, letting your guitar stand out in the mix.
EMG includes an output jack and battery clip set with the EXG Guitar Expander EQ Knob.
