carl martin contour & boost is especially designed to boost up, and change the sound (contour) of electric guitar/bass.
the contour & 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 & 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 & 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 & boost after any distortion units, otherwise the distortion unit will limit what you can achieve with the contour & boost.
