Carl Martin Contour’n Boost is especially designed to boost up, and change the sound (contour) of electric guitar/bass.
The Contour’n Boost circuitry is of phase linear design, using high quality components. This ensures sonic clarity and midrange emphasis which is so important for electric guitar.
The Contour’n Boost is designed as a High Pass (low cut) and Low Pass (high cut) filter, with a fixed X-over frequency at 440Hz. The High Pass filter operates from 65Hz to 440Hz, and the Low Pass filter from 440Hz to 8kHz. Both filters are individually sweepable, with a boost range of up to 12dB. With these two filters it is possible to change the sound (contour) in any way your creativity allows you.
The Carl Martin Contour’n Boost has a built in, regulated (+-12V) power supply which enables us to design circuitry of the highest quality with maximum headroom.
Please note that when using this unit with other effect devices, always place the Contour’n Boost after any distortion units, otherwise the distortion unit will limit what you can achieve with the Contour’n Boost.
