For flexibility in tone at your fingertips there is no better choice than the EXG Guitar Expander. 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.
Package includes: Output jack and battery clip set.
