Boost-EQ

The Diamond Boost-EQ is a low-noise discrete transistor-based clean boost with an innovative EQ section. The EQ borrows the powerful tilt equalization control from the Diamond Compressor and adds a new midrange cut/boost control for simple yet powerful tone shaping with just two knobs. The Boost-EQ features up to a 16dB signal boost, which can push most tube amp input stages well into overdrive territory, but with a wider frequency range and more responsive feel than standard diode clipping overdrive pedals. The boost-EQ’s simple goal is to enhance the natural drive character of a guitar amp’s tubes, anywhere from a light clean solo boost with 2-4 dB of gain to heavier tube breakup with higher level boost.

Key features and technical specifications include:
- Premium audio components, including 2% polypropylene capacitors, 1% metal film resistors, and a pro audio grade opamp.
- Post-boost ’tilt’ EQ provides a very musical tailoring of frequency response, allowing for a seamless transition from a darker jazz voicing to a brighter jangle, with flat frequency response at the center detent position.
- Midrange cut/boost EQ placed at the fulcrum of the tilt EQ for a unique parametric EQ response.
- Dual AC capacitive coupling paths for improved transient response.
- True bypass signal path.
- Battery or standard negative tip 9V DC adapter operation, can be powered from 9 to 18 V negative tip.

The Boost-EQ is designed to provide a transparent clean boost and versatile EQ shaping for guitarists seeking to enhance their tone and drive character.
