PROJECT NAME
ANDROMEDA DELUXE
BASED ON
Nordland ODR-C
EFFECT TYPE
Overdrive
PROJECT SUMMARY
An updated version of the definitive Nashville overdrive, handmade by the original circuit designer,
adding three new controls and a number of other small refinements.
Actual size is 2.3" x 2.42" (main board) and 1.78" x 0.86" (bypass board).
This documentation is for the Deluxe version of the project. Please make sure your PCB matches
the above image (a larger board with six knobs) before proceeding since the part numbering is
different. The

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. -

The original ODR-C uses the 2N5486 (MMBF5486) JFET for Q1, which is no longer in active production. This is very similar to the 2N5457, which is available from Aion FX in SMD format pre- soldered to through-hole adapter boards and will perform identically in this circuit. -
