Carl Martin 3 Band Parametric EQ
Carl Martin · pedal
The Carl Martin 3-Band Parametric EQ is a three-band parametric equalizer pedal offering independent Frequency, Level, and Q (bandwidth) controls per band for surgical tonal shaping. Parametric EQ allows precise selection of center frequency and bandwidth width unlike fixed-frequency graphic EQs. Carl Martin is a Danish boutique manufacturer known for high-quality analog circuits. Suited for studio recording, live sound correction, and advanced tonal sculpting for guitar and bass players who need more precise EQ control than standard amp tone stacks provide.
