The Maxon TBO-9 True Tube Booster OD utilizes the same "pre-tube" configuration as the TOD-9. However, the TBO-9 also features the Dry Blend feature found in Maxon's popular OD820 and VOP-9 overdrives.
The Drive Control has the dual function of increasing saturation and blending clean signal in against the distorted sound. At zero, the Maxon TBO-9 is passing pure clean tone, but this signal can be altered using the Gain and Tone controls of the pedal, effectively creating a tube preamp/booster.
As Drive is increased, saturated signal is blended in against the clean tone, realizing a 50/50 mix at the 12 o'clock position. At fully clockwise position, the TBO-9 acts as a tube overdrive, much like the TOD-9.
Using the TBO-9, a wide range of tube booster/overdrive tones can be achieved, all of them yielding the warm, organic tube tone that every guitarist craves.
