This is a custom two channel version of the Warhol, Chris will not make them like this anymore. This has a tilt style EQ as well as his Pollock compressor on each channel. The Warhol is a high voltage mosfet preamp with just as much character as the tube HendyAmps preamps.Although the controls are limited, sound wise each channel has a full fledged Pollock compressor. You can switch between normal compression, or just compressing your high frequencies. Although it's an amazing de-esser, it's versatile enough to be used to take some edge off of any source (like brighter microphones).
Here is a link of me reviewing this preamp.
