INTRODUCTION
The Andromeda Deluxe is an adaptation of the Nordland ODR-C, a boutique overdrive
, based on the Nobels ODR-1.
The ODR-1 was originally released in 1992, designed by Kai Tachibana as an original circuit for Nobels.
Intended as a budget alternative to the Tube Screamer, the build quality was less than stellar, but to
those who played it, it was undeniable that the circuit itself was something special. It steadily increased
in popularity over the following decades until the present when it’s often seen in lists of the top 10
overdrives of all time.
In 2019, Kai decided to revisit the ODR-1 and update it with a few new features under his own Nordland
brand name. The result is the ODR-C Custom Overdrive, a brilliantly-designed handmade pedal that
occupies the opposite end of the spectrum from the ODR-1 in both build quality and price. It features
three new controls: a low cut that fixes the bass-forward tone of the original, a midrange control that
can boost or cut, and an “overdrive de-compress” (ODC) control that gradually adds higher-threshold
clipping diodes in the soft-clipping stage. Each of the three knobs can be set to a position that emulates
the original ODR-1, so the core circuit is the same change despite all the added features.
The Andromeda Deluxe is based on the audio path of the ODR-C, only cutting out the complex polarity
protection and LED dimmer circuit. Side by side, they should sound the same. But we’ll reiterate that
the original ODR-C is fantastic piece of engineering and it’s worth it if you can find one. Check out the
tracing journal if you want to see what we’re talking about.
USAGE
The Andromeda Deluxe has six controls:
•
Gain
controls the amount of gain from the op-amp that is fed through the feedback clipping diodes.
•
ODC
(Overdrive De-Compress) blends in higher-threshold LEDs in the feedback clipping section.
•
Spectrum
pans between a 700 Hz lowpass filter and a 5 KHz high-pass filter, which is mixed with a
fixed 2.1 KHz frequency boost (upper mids).
•
Low Cut
blends between two different bass filters to reduce the low-end that is characteristic of
the original ODR-1.
•
Mid Boost
boosts or cuts frequencies at around 1kHz, with a flat response in the 12:00 position.
•
Level
sets the overall output of the effect.
