The AGRO is based on the saturation channel of Aguilar`s celebrated AG 500 bass head. Capable of producing everything from warm, tube-like overdrive to full on distortion, this pedal will give 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. The output level control guarantees that you`ll be able to get the distortion you want at any volume level.
