 The Maxon TBO-9 True Tube Booster/Overdrive employs a pre-tube configuration similar to the TOD-9. It includes the Dry Blend feature available in Maxon’s famed VOP-9 and OD820 overdrives. It consists of Boost, Drive, Level, and Tone knobs. The Boost control lets you adjust the tube gain level while the dual-purpose Drive knob increases saturation and blends clean signal and distorted sound. The TBO-9 combines overdrive and clean boost functionalities with a tube gain stage to give you a flexible tone-sculpting tool.
