■This is the world's smallest tube booster/overdrive effect pedal, featuring an ultra-compact military-grade reliable vacuum tube housed in a compact 9 Series case. (Based on maxon research as of January 2008) It produces a comfortable, powerful tube sound that is difficult to replicate with digital processing simulators.
■It produces a wide range of excellent tube sounds, from natural boosts that take advantage of the sonic character of your guitar or amplifier to sustained overdrives with a distinctive midrange.
■The 9V voltage supplied by the AC adapter is boosted to 30V internally and then supplied to the tube and overdrive circuits. Ample dynamic headroom significantly reduces unintentional distortion, ensuring consistently stable, high-quality sound.
■ Equipped with TBS (True Bypass Switching) using a 4PDT mechanical switch, the unit enters a completely bypassed state, with no electronic circuitry involved. Even when using effects, there is no degradation in sound due to the switching circuit.
■ Equipped with a heater inrush current control circuit to extend the life of the vacuum tubes.

*The TBO9 does not operate on batteries. It operates using the included AC adapter.
