DOA Discrete Opamp Colour Kit
- Full Kit
- Step-by-Step Guide
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 (ex: Melcor 1731) to fast and clear (ex: John Hardy 990). 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 several DOA options:
- Whistle Rock Audio "BLU-18" - Jensen-style kit
