Effect what you will, and boost what you will effect. The Augustine Clean Boost V2 is based on the revered but out-of-production TC Electronic Integrated Preamp and shares its core circuit with the Zurich Preamp. Boasting an internal 18V charge pump for maximum beefiness and two-band EQ, the Augustine Clean Boost V2 is fantastic as an always-on preamp, solo boost, or boost in front of a high gain amp.
