This was modded with a blend pot (where the volume used to be) and the volume was moved above the battery compartment (inside) to a trim pot. Pedal works great......just used it for the past few months gigging it and no issues.....moving back to my blended rat that I used to use though.....I just like it better. Description of the stock pedal characteristics: "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."

Chorus pedal possibly? Hit me up with an offer.
