Capable of producing everything from warm, tubelike overdrive to full-on distortion, the aguilar AGRO Bass Overdrive Pedal gives you the grind you need without sucking out your low end. The AGRO offers a wealth of overdriven sounds within an easy-to-use 4-knob layout. The Saturation control offers a tremendous range of distortion, while the Contour control allows you to dial in a scooped or a more aggressive boosted midrange sound. The Presence knob adds the right amount of attack, ensuring that your bass remains defined even with the most saturated settings, while the output Level control guarantees that you'll be able to get the distortion you want at any volume level.
