The "ODR-C" is the ultimate update of the ODR-1 effect pedal, developed by Kai Tachibana in the early 90s, which has been established in the USA/Nashville scene for years. Kai corrected a few youthful sins in the technical design - without changing the sound. In addition, he installed the following controls:
Lo-Cut: to reduce the bass frequencies
Mid: center control
O.D.C.: (Overdrive De-Compress) to decompress the overdrive-stage
LED brightness: (inside!) To adjust the brightness
It is called ODR-C, C like Custom, and is soldered by hand, assembled and of course checked by Kai Tachibana himself.
