The TS9B is equipped with controls that allow bassists to preserve the low-end frequencies they need, while still maintaining the feel and tone of the original Tube Screamer. Experimenting with the mix and tone controls allows for a limitless number of sounds and textures. Players can go from just "a little bit of grit" to "full-on" overdrive and everything in-between.
