The Andromeda is an ODR-1 overdrive. It features 4 controls. Gain controls the amount of gain from the op amp that is fed through the feedback clipping diodes. Level is the output level of the effect. 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.
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 the standard hi-cut or Tube Screamer style tone control.
This kit contains the PCB and all necessary parts. The enclosure can be selected, please select 4 knobs for 6,3mm shaft separately.
