The One Control Hooker's Green Bass Machine 4K has a dynamic range as wide as a bass tube amp and picks up all the subtle expressions that bassists create with their fingers. Transitions between clean and distorted sounds are smooth and it creates a gorgeous but stable compression tone like an old transistor amp when you increase the distortion. It won't miss any finger touches and accurately produces any groove from blues, fusion, or hard rock to metal. Its moderately sharp attack and clear sounding keys do not decrease the speed realized by picking. With slapping, percussive chunks of sound by thumbing pop up, and sound created by pulling can be maintained and kept stable. The ability to freely control distortion enables you to play in a relaxed and comfortable way. For heavy tracks using a multi-string bass, the Low Boost control does its job. The OC Hooker's Green Bass Machine 4K has enough low-end, but if it's not enough, adjust the Low Boost to unlock even more low-end. The Treble knob has a limited range to allow subtle adjustment. Many music venues and studios have modern bass amps equipped with powerful EQ and basic bass sound is created using that. What is required for an overdrive pedal is delicate sensory adjustment that is impossible with amp EQ. This pedal can also be used as an overdrive pedal when paired with a guitar.
