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.
