Crazy Tube Tube Driver Overdrive Circuits/Venus

●A real tube overdrive inspired by all pedals and rack versions of the BK Butler Tube Driver. ●Compact housing less than half the size of a classic tube drive unit. ECC832 vacuum tubes (half ECC83 and half ECC82) are used for optimal performance. ECC83/12AX7, 5751, ECC81/12AT7, 6072/12AY7, and ECC82/12AU7 can also be used instead of the ECC832. Power supply: DC 9V, center negative power supply with a current capacity of 500mA or more ●Operates internally on ±15V DC (via internal boost and inversion circuits), just like the classic vacuum tube drive units it is inspired by. ●Maximum current consumption 400mA ●Clickless true bypass design with high-quality relays Footswitch power-up, bypass, and preset functions ●Top mount jack Dimensions: (W x L x H): 126 x 66 x 57 mm Weight: 317g Venus is a true tube overdrive pedal inspired by all pedal and rack versions of the BK Butler/Chandler Tube Driver. It produces everything from smooth, light overdrive tones to high-gain, nasty distortion. With ultimate versatility and tone sculpting in mind, we set out to recreate one of the pedal museum's greatest masterpieces with modern refinements. Without sacrificing tone, we packed the circuit into the smallest possible enclosure—less than half the size of the original pedal unit. The Tube Driver is a unique overdrive design that uses vacuum tubes, operating in a "starved plate" setup. The power supply of the original design was built with an internal step-down transformer to reduce the line voltage to +/-15V DC, which typically introduced a lot of background noise and hum. To minimize these issues, we chose to power Venus from a standard 9V DC power supply. 50 The pedal can be operated from an isolated DC 9V center negative power output that can supply 0mA of current. A properly designed internal boost/inverter circuit then provides the correct voltage conditions (DC ±15V) for vacuum tube operation. Controls Drive: Controls the amount of vacuum tube drive/saturation and sustain. Bias: Sets the vacuum tube cathode bias depending on the type of vacuum tube and the texture of overdrive/distortion. Volume: Sets the output level of the effect. 3-band EQ (Hi, Mid, Lo). Fat/Tight push switch. Line driver/buffer + booster push switch.
