Add the sound of any discrete opamp to your Palette.

Discrete opamps (DOAs), such as the API 2520, are at the heart of countless pieces of classic gear. Every DOA has it's own tone, from slow and dark to fast and clear. And DOAs are largely responsible for the recognizable sound of many consoles, preamps, etc.

The DOA Colour allows you to plug any DOA into your Palette and tailor the amount of saturation you desire. You can purchase the DOA Colour on its own or bundled with the RED-25 DOA.
