The Carl Martin 3 Band Parametric Pre-Amp was developed for musicians who play acoustic instruments through a combo amp and require a high quality EQ and balanced line driver. These features have been integrated into a convenient stompbox format with both XLR and quarter inch outputs. The unit also works well for tweaking the sound of electric guitars, basses and other electronic instruments in the studio. Has a built in regulated power supply.
