1 Project Overview

2 Introduction & Usage

INTRODUCTION

The Andromeda Natural Overdrive is a recreation of the Nobels ODR-1, a somewhat obscure pedal

from Germany that nonetheless is considered a "secret weapon" among Nashville studio musicians.

The primary complaint of the ODR-1 is that it has way too much bass with no way to dial it out. To that

end, this project incorporates a variable bass control inspired by the Timmy and Zendrive. The stock

tones are still there with the knob all the way up, but now you have the option to dial it back.

Looking at the schematic, you can see a stark difference with Japanese-designed pedals (i.e. most Ibanez

& Boss circuits). This is German engineering at its finest-tons of odd-value resistors and capacitors

forming very precise filters and signal shaping. This is not a particularly simple build, but it's very

rewarding and well worth the effort.

The new 125B version of the Andromeda has a new layout but is otherwise identical to the earlier

1590B version. No features were added or removed.

USAGE

The Andromeda has four controls:

• Gain controls the amount of gain from the op amp that is fed through the feedback clipping diodes.

• Spectrum is a very non-standard tone control of sorts. You can pan 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). This

control is much more complex than your standard high-cut or Tube Screamer style tone control.

• Bass allows you to adjust the bass response of the circuit. The stock ODR-1 circuit is the equivalent

of having the Bass knob turned all the way up.

• Level sets the overall output of the effect.
