tube overdrive pedal

Posted on Feb 7, 2014

That circuit is similar in concept to the BK Butler/Tubeworks Tube Driver. Since there is only a 9v supply, the tubes operate in `starved plate` mode. Preamp tubes normally operate on 100v-300v. It`s similar to using a Variac on a tube amp. When there is only 9v on the anode the tube operates way outside its linear amplification range and is easy to push into distortion. Guitars
