Designed to be versatile without compromising tonal integrity, The Cartographer by Matthews Effects is perfectly simple yet exceptionally powerful parametric overdrive. Its main EQ components are just two knobs, Freq and Cut/Boost, both of which are aptly titled. The frequency control sweeps through the dynamic range while the cut/boost knob provides either one, depending on which side of 12 o'clock the player dials in. The output provides a volume boost while the gain knob adds some grit, making it the perfect pedal to put in front of any pedalboard, to be used as a full-on overdrive, or just a great-sounding EQ before hitting the next gain stage.
