MXR M81 Bass Preamp

Effect pedal for electric bass guitar that combines a pristine bass preamp with a studio-quality Direct Out in a Phase 90-sized box, providing clear tone without hogging precious pedal board space. It can be used to add a new voice to an old passive bass, sweeten up any amp, or put some special sauce on a particular song. It can be dial it in any way and send straight to the house – pre or post-EQ – with the built-in Direct Out. Pedal features separate INPUT and OUTPUT level controls and a 3-band EQ section with sweepable midrange (from 250 Hz to 1kHz) for extensive tonal flexibility. It is all delivered super clean with high headroom thanks to the Constant Headroom Technology, while PRE/POST EQ switch can be used to set whether or not the Direct Out signal is affected by the pedal’s EQ section.It also features a GROUND LIFT switch in case of ground loop hum. Pedal is factory preset to operate in 1/4” out buffered bypass and Direct Out active. For players who only want to use the 1/4” out, there are two internal switches that disable the Direct Out and 1/4” out buffered bypass for true 1/4” out bypass mode.
