The TS9B Bass Tube Screamer is equipped with controls to allow bassists to produce the sound they want while still maintaining the feel of the Tubescreamer. Experimenting with the mix and tone controls allows for creation of a limitless number of sounds. Players can get a tight, fuzzy sound with mix control or a mid-scooped, funky sound with 2-band control.

The TS9B is powered by a 9V battery or optional (sold seperately) AC adapter.
