Throbak has reproduced and improved the circuit of the original Colorsound Overdriver (also known by the name Power Boost). The original was used by Jeff Beck and was an integral part of his 70's signature tone. The Colorsound Overdriver was also a favorite of Marc Bolan and is considered by many to be the best overdrive/booster ever made.
This vintage circuit was made popular for it's ability to bring body, dimension and tonal flexibility to a single channel tube amp. This Silicon transistor circuit can give everything from a substantial and extremely transparent clean boost to all out silicon fuzz and every tonal variation in between. The flexible and interactive bass and treble controls can add treble bite and chime to a overly bassy amp or add a meaty low end to an amp that sounds too thin. This pedal is almost like it's own little amp in a box that will bring amazing clean and distorted tones to any tube amplifier.
In keeping with our Signature sound philosophy we have added several improvements and tweaks to the pedal that let you tailor your own signature sound with this tonal giant. First we have added a master volume. The original Colorsound Overdrivers usually lacked a master volume control so we added one to the Overdrive Boost. As with the Throbak Fuzz Haze and Stone Bender a Pre Gain switch has been added giving more control to low note definition of distorted tones. Thirdly a switchable Germanium transistor has been paired with a Germanium diode and added to the circuit. The original circuit remains in tact but when switched on, the Germanium pair adds flexibility way beyond that of the original Colorsound Overdriver, adding the edgy, compressed distortion tones you can only get from Germanium.
In addition to these features each silicon transistor has it's own internal trim pot to ensure that each pedal is perfectly tuned.
