Flagship Tube Mic and Instrument Preamp

Robbie is a Class-A discrete tube preamp that reveals the true tone of your voice or instrument. Featuring audiophile-grade components and an IC-free signal path, Robbie the Mic Pre delivers superior accuracy and transparency every time. With an unprecedented 34dB of headroom before clipping, Robbie will add depth and dimensionality to your recordings.

Robbie puts an end to the tube vs. solid-state debate by combining the best aspects of each into one premium preamp. The fully discrete ECC88 twin triode tube input and gain stage deliver warm, rich and detailed tone, while the electronically balanced solid-state output ensures pristine sound with unmatched clarity. Together, it's two halves of the same whole of audio quality - aka, perfection.

Robbie is all about incredible audio quality without limits. With a massive 34dB of headroom before clipping, plus hand-tuned components that maintain the integrity of your sound, Robbie helps you record your music the way you've always imagined - powerful, precise and pure.
