ODR-CS

In 1993, Tachibana designed the ODR-S as a warmer alternative to his 1992 ODR-1, using germanium diodes instead of silicon and adding a 3-band equalizer. That circuit disappeared for decades until he revived it as the ODR-CS Custom Special under his Nordland brand, finally sourcing the necessary components in 2020-2021.

The germanium hard-clipping stage follows a silicon-based overdrive stage, with the G.D.C. (Germanium Drive Control) modulating the germanium diode contribution. The signal path is JFET input (capacitor-free), filter, overdrive, germanium clipping, 3-band EQ (bass/mid/treble with true boost-and-cut mid), output filter, and volume. This differs fundamentally from the ODR-C's topology.

Running on 9-18V (15mA at 9V, 25mA at 18V) with voltage-dependent tonal characteristics, the ODR-CS weighs 360g in its Hammond aluminum enclosure. True bypass with adjustable LED brightness, 1% resistors, 5% film caps, gold-plated everything. The warm, germanium-flavored ODR evolution.
