D312A Distortion Filter
The Great Eastern FX Co. Distortion Filter D312A is a limited-edition effects pedal, produced in a run of only 165 pieces. It is part of the brand's Obsolete Devices series, designed to combine classic hard-clipping distortion with a potent band-pass filter for unique sound shaping. The core of the pedal's circuit is built around a distinctive trio of Soviet-era germanium pulse diodes, identified by the part number D312A. This design choice contributes to its specific vintage character and tone. The pedal is powered by a 9V DC mains adapter and has a low current draw of 10mA, making it pedalboard-friendly. The D312A is celebrated for offering complex distortion textures not typically found in modern circuits.
